Question 4 |

When buying an item, a man was given a 10% discount on its original price, and then he was charged a 10% tax on its selling price. Base from this transaction, which of the following is true?

A | The original price and the selling price are the same. |

B | The amount paid is 20% lower than the original price. |

C | The amount paid is 10% lower than the original price. |

D | The amount paid is 99% of the original price. |

Question 4 Explanation:

let OP = original price
discounted price = OP – 0.1OP = 0.9OP
tax = 0.9OP x 0.1 = 0.09OP
amount paid = discounted price + tax = 0.9OP + 0.09OP = 0.99OP

Question 5 |

The ratio of men to women at a concert was 2:3. If there were 350 people in the concert, how many women were there?

A | 140 |

B | 200 |

C | 150 |

D | 210 |

Question 5 Explanation:

2:3, ratio of men to women. Let k = constant which we will use as multiplier to the ratio
2k + 3k = 350
5k = 350
k = 350/5
k = 70
the total number of women in the concert is (70)(3) = 210

Question 6 |

A fruit salad mixture consists of apples, banana and peaches in the ratio of 6:5:4 respectively by weight. If 225 grams of mixture is prepared, how many more grams of apples than peaches?

A | 30 |

B | 60 |

C | 45 |

D | 75 |

Question 6 Explanation:

6:5:4 – ratio of apples, banana, & peaches respectively. Let k = constant which we will use as multiplier to the ratio
6k + 5k + 4k = 225
15k = 225
k = 225/15
k= 15
weight of apple = (6)(15) = 90, weight of banana = (5)(15) = 75,
weight of peaches = (4)(15) = 60
weight of apple – weight of peaches = 90 – 60 = 30 grams

Question 7 |

*r*,*s*,*t*are three consecutive integers such that*r*>*s*>*t*, then (*r*–*s*)(*s*–*t*)(*r*–*t*) equals:A | 0 |

B | -1 |

C | 2 |

D | -2 |

Question 7 Explanation:

Given three consecutive integers: r, s, t and r > s > t. let r = 3, s = 2, t = 1
(r-s)(s-t)(r-t)
= (3-2)(2-1)(3-1)
= (1)(1)(2)
= 2

0.3x = 63
x = 63/0.3
x = 210

Question 9 |

Lovely’s grade in four of her quizzes are 83, 86, 89, and 90. There is one more quiz for the grading period and she does not want an average lower than 85, what is the lowest possible grade that she can get on her fifth quiz to maintain that average?

A | 77 |

B | 75 |

C | 79 |

D | 81 |

Question 9 Explanation:

[83+86+89+90+x]/5 = 85
[348 + x]/5 = 85
x = 77

Question 10 |

What is the value of the digit

*x*in order for 5719*x*to be divisible by 2, 3 and 6?A | 6 |

B | 0 |

C | 2 |

D | 7 |

Question 10 Explanation:

5719x to be divisible by 2, 3, and 6 must follow the divisibility rule for 2, 3, and 6.
Divisibility rule for 2: last digit must be an even numbers (0, 2, 4, 6, 8)
Divisibility rule for 3: sum of all digits must be divisible by 3.
Divisibility rule for 6: must follow the divisibility rule for 2 and 3.
Applying the divisibility rule for 6, we now get the sum of all digits to check if this number is divisible by 3.
5+7+1+9+x = 22+x, since we need an even number for the last digit so that it can be divisible by 2, x = 2 so that
22 + 2 = 24, 24 is divisible by 3.

Question 11 |

Tuwing bakasyon, ginagamit ni Leah ang 30% ng kanyang oras sa pagbabasa ng mga nobela. Sa kabuuan, kaya niyang matapos ang isang nobela ng pitong oras. Kung siya ay natutulog ng siyam na oras araw-araw, ilang nobela ang kaya niyang tapusin sa loob ng dalawang linggo?

A | 7 |

B | 9 |

C | 5 |

D | 8 |

Question 11 Explanation:

24 hours – 9 hours (sleeping) = 15 hours (awake)
30% of 15 hours = 0.3 x 15 = 4.5 hours per day reading a novel
4.5 x 14 days/2 weeks = 63 hours reading novels in 2 weeks
63 7 hours/novel = 9 novels she can read in 2 weeks

Question 12 |

The sum of five consecutive integers is 35. How many of the five consecutive integers are prime numbers?

A | 3 |

B | 1 |

C | 4 |

D | 2 |

Question 12 Explanation:

five consecutive integers: x, x +1, x + 2, x +3, x + 4
x + [x+1] + [x+2] + [ x+3] + [x+4] = 35
5x + 10 = 35
x = 5
so the five consecutive integers are: 5, 6, 7, 8, 9
let check if their sum is 35: 5 + 6 + 7 + 8 + 9 = 11 + 7 + 8 + 9 = 18 + 8 + 9 = 26 + 9 = 35
the prime numbers are 5 and 7.

n is any integer, let n = 1 for odd numbers & n = 2 for even numbers.
If n = 1,
A. n, n + 1, n + 3 = (1), (1) + 1, (1) + 3 = 1, 2, 4 not consecutive odd integers
B. n, n + 2, n + 4 = (1), (1) + 2, (1) + 4 = 1, 3, 5 consecutive odd integers
C. 2n + 1, 2n + 2, 2n + 3 = 2(1) + 1, 2(1) + 2, 2(1) + 3 = 3, 4, 5 not a consecutive odd integers
D. 2n + 1, 2n + 3, 2n + 5 = 2(1) + 1, 2(1) + 3, 2(1) + 5 = 3, 5, 7 a consecutive odd integers
If n = 2,
A. n, n + 1, n + 3 = (2), (2) + 1, (2) + 3 = 2, 3, 5 not consecutive odd integers
B. n, n + 2, n + 4 = (2), (2) + 2, (2) + 4 = 2, 4, 6 not consecutive odd integers but consecutive even integers
C. 2n + 1, 2n + 2, 2n + 3 = 2(2) + 1, 2(2) + 2, 2(2) + 3 = 5, 6, 7 not consecutive odd integers
D. 2n + 1, 2n + 3, 2n + 5 = 2(2) + 1, 2(2) + 3, 2(2) + 5 = 5, 7, 9 consecutive odd integers
D satisfy both sample value for n.

Question 15 |

Simplify the expression: 5y – {3y + (2y – 5) – [3 – (2 + 4y)]}

A | 4y |

B | 6 – 4y |

C | 14y – 6 |

D | 4y + 6 |

Question 15 Explanation:

5y – {3y + (2y – 5) – [3 – (2 + 4y)]}
= 5y – {3y + (2y – 5) – [3 – 2 – 4y)]}
= 5y – {3y + 2y – 5 – (1 – 4y)}
= 5y – {3y + 2y – 5 – 1 + 4y}
= 5y – (9y – 6)
= 5y – 9y + 6
= 6 – 4y

A | 4 |

B | 18 |

C | 6 |

D | 12 |

Question 17 Explanation:

Let the present age of Jennilyn be equal to x.
Present age = x
3 years ago = x-3
6 yrs from now = x +6
x – 3 = ¼ (x + 6)
4(x – 3) = x + 6
4x – 12 = x + 6
3x = 18
x = 6 , Jennilyn is 6 years old

Question 24 Explanation:

six consecutive integers: x, x +1, x + 2, x +3, x + 4, x + 5
sum of first three terms:
x + [x+1] + [x+2] = 27
3x + 3 = 27
3x = 24
x = 8
so the six consecutive integers are: 8, 9, 10, 11, 12, 13.
The sum of last three integers: 11 + 12 + 13 = 36

Question 25 |

Two cars traveled at the rates of 50 kph and 60 kph respectively. The faster car traveled 2 hours longer than the slower car and went 150 kms farther. Find the time traveled by the slower car.

A | 3 |

B | 7 |

C | 5 |

D | 4 |

Question 25 Explanation:

Rate x Time Distance
Faster Car:
rate = 60
time = t + 2
distance = d + 150
Slower Car:
rate = 50
time = t
distance = d
60(t + 2) = d + 150 , 50 t = d
60t + 120 = 50t + 150
60t – 50t = 150 – 120
10t = 30
t = 3 hours

Question 26 |

Determine the equation of the line which passes through (4, -2) and has a slope of 3.

A | y = 4x - 2 |

B | y = -7x + 5 |

C | y = 3x - 42 |

D | y = 3x - 10 |

Question 26 Explanation:

Use point-slope formula,
y - y1 = (x= x1)m
y – (-2) = (x – 4)(3)
y + 2 = 3x – 12
y = 3x – 10

Question 27 |

A | 20 |

B | 50 |

C | 40 |

D | 30 |

Question 27 Explanation:

let x = original number of packages before the 1st delivery
[4/5]x - 9 = [1/2]x
[4/5]x - [1/2]x = 9
[(8-5)/10] x = 9
x = 90/3
x = 30

Question 28 |

Mrs. Isagani can embroider a tablecloth in 10 days while Mrs. Rosas can embroider the same tablecloth in 2 ½ days. How long will it take both of them to embroider one such tablecloth?

A | 5/13 days |

B | 1/2 days |

C | 7/10 days |

D | 2 days |

Question 28 Explanation:

Mrs. Isagani:
rate = 1/10
time = x
work = x/10
Mrs. Rosas
rate = 5/2
time = x
work = 5/2 x
The work Mrs. Isagani and Mrs. Rosas did together equals one whole job = x/10 + 5x/2 = 1
Manipulating the equation,
x + 25x = 10
26x = 10
x = 10/26 or 5/13 days

🙂

hi po… don’t be offended pero ang hirap pong intindihin ng mga explanations kasi po walang mga kama na nagseseparate sa mga equations, i think. please work on that. pero thank you pa rin po. big help…

Agree!!

For this question..

“Determine the equation of the line which passes through (4, -2) and has a slope of 3.”

Y-(-2)=3(x-4)

Y + 2 = 3x – 12

Shouldn’t the answer be : y= 3x-14 , instead of y= 3x -10???

I don’t get it… 🙁

By the way, I really really love these quizzes!!! I learned a lot because of these.

lol I can’t even understand some of the explanations/solutions *needs more practice 🙁

ang hirap naman nento.. Haha LAlo na yung basic math test. HAha bobo ko talaga

Need more practice :\

thanks a lot because i pass the upcat 2013

Great job. Congratulations! 🙂

*passed

Nakakalito ba talga yung ibang questions o bobo lang tlga q? Lol

Nasan ung sample test

Congratulations – you have completed Basic Math Quiz. You scored 30 out of 30. Your performance has been rated as Perfect! I LOVE MATH! PROUD TNHSian!

yes!

13/30 ang score ko !

hindi na rin masama.

pero mababa parin hindi pa yun makakapasa sa UPCAT.

Thanks God.

Andami ko nanaman natutunan.

hello !

basic in mathematics test, is very hard for me !

may iba naman na mali ang solution. Example sa number 15 dapat ang solution is: let x be r, x+1 be s, x+2 s,

so,

=[x-(x+1)][(x+1)-(X+2)][x-(X+2)]

=(x-x-1)(x+1-x-2)(x-x-2)

=(-1)(-1)(-2)

=-2

Tama naman eh. Mas madali pag binibigyan mo ng value kesa gagamit ka ng variable. Try mo!

Akala ko rin mali ako pero r>s>t pala haha

mm. 21 lhan. :/

oh my gosh basic math i cant pass 😐 sucks !

was it harder sa actual upcat?: )

Sa 19 naman, ang liwanag nung sentence na “sixty-seven less than the sum of fifty-eight and forty-two” 67- (58+42) . kaya ang labo pano naging (58+42) – 67? hahaha. Buti sana kung nakalagay sa question eh “Sixty-seven subtracted to the sum of fifty-eight and forty-two”

Tama naman eh. Mas madali pag binibigyan mo ng value kesa gagamit ka ng variable. Try mo!

Tama naman ah. 🙂 Parang 27 more than x = x+27. Jan naman, parang 67 less than 100 = 100-67. Jan din ako mali, pero narealize ko mali ko. 😀

Tama na (58+42) – 67. Kasi sabi naman less than eh. Kung hindi less than yan, tsaka ka magreason kung bakit ganun.

sana dun sa #13 po nilagay mo instead of “seventy-five multiplied twice” eh seventy-five multiplied twice itself. kasi malilito talaga ang magte-take, parang grammar error kasi mam.

yung number 23 po, diba dapat answer dun eh y=3x-14?

Ohhh!!! Same yung sagot ko… Feeling ko yan talaga yung sagot. Baka natypo lang. Hehe

Yung sa question po na

“For any integer n, which of the following represents the sequence of three consecutive odd integers?”

Ito po yung binigay na solution:

n is any integer,

let n = 1 for odd numbers & n = 2 for even numbers.

If n = 1,

A. n, n + 1, n + 3 = (1), (1) + 1, (1) + 3 = 1, 2, 4 not consecutive odd integers

B. n, n + 2, n + 4 = (1), (1) + 2, (1) + 4 = 1, 3, 5 consecutive odd integers

C. 2n + 1, 2n + 2, 2n + 3 = 2(1) + 1, 2(1) + 2, 2(1) + 3 = 3, 4, 5 not a consecutive odd integers

D. 2n + 1, 2n + 3, 2n + 5 = 2(1) + 1, 2(1) + 3, 2(1) + 5 = 3, 5, 7 a consecutive odd integers

If n = 2,

A. n, n + 1, n + 3 = (2), (2) + 1, (2) + 3 = 2, 3, 5 not consecutive odd integers

B. n, n + 2, n + 4 = (2), (2) + 2, (2) + 4 = 2, 4, 6 not consecutive odd integers but consecutive even integers

C. 2n + 1, 2n + 2, 2n + 3 = 2(2) + 1, 2(2) + 2, 2(2) + 3 = 5, 6, 7 not consecutive odd integers

D. 2n + 1, 2n + 3, 2n + 5 = 2(2) + 1, 2(2) + 3, 2(2) + 5 = 5, 7, 9 consecutive odd integers D satisfy both sample value for n.

Yung sagot po dito ay 2n + 1, 2n + 3, 2n + 5. Pero di po ba dapat n, n + 2, n + 4 yung sagot? Bakit po sinama yung n=2 e diba po even yun? Thankyou. 🙂

“For any integer n” kasi

PLEASE look at this question.

Which of the following set of fractions arrange in ascending order?

A. 5/12, 1/9, 7/8, 11/8

B. 3/16, 1/7, 2/5, 5/6

C. 13/15, 1/4, 3/8, 5/6

D. 6/19, 7/12, 3/4, 4/5

Question 23 Explanation:

A. 0.416, 0.111, 0.875, 0.611 not in ascending order B. 0.187, 0.143, 0.400, 0.833 not in ascending order C. 0.316, 0.583, 0.750, 0.800 in ascending order D. 0.867, 0.250, 0.375, 0.833 not in ascending order.

The right answer was letter D. according to the reviewer but the real answer is letter C.

Same happened to me. Pero yes, D ang tamang sagot. :))

Q#5: As you explained, the amount paid = 0.99OP. so that means the amount paid is 1% (not 10%) lower than the original price, or equivalently, the amount paid is 99% of the original price.

Q#25: Please check the last part of your computation. If y+2=3x-12 then y=3x-14

Q#27: The equation should be x/10 + 2x/5 = 1 . The second term should not be 5x/2. so the answer should be 2 days.

I agree with you and Bankai.

Question 23, 5, 25 and 27 have errors. 🙂

You’re my hero!

i think there’s something wrong in the question in determining the equation of the line which passes through (4,-2) and has a slope of 3

in getting the slope we use the formula: y=mx+b

substituting now given x as 4, y as -2 and m is 3

-2=(3)(4) + b

-2=12 + b

-14=b

the answer should be

y=3x-14

just saying 🙂

im sorry it’s getting the equation of the line the formula is y=mx + b not getting the slope

also getting the same answer (y=3x-14)

In the question Determine the value of k so that the line kx – 8 + 7y = 0 will be parallel to the line 2x – y + 1 = 0…

The given answer is -14…

If so, given that answer isn’t it asking for the value of k so that it would be PERPENDICULAR to line 2x-y+1=0.

I’m not a math whiz like the rest of you here so I only checked…

Like I was saying, it was asking for a line perpendicular to the given equation. Why?

I tried getting the x and y coordinates of -14x -8 + 7y.

X coordinate

-14x -8 + 7(0) = 0

-14x = 8

x = -14/8 or -7/4

Y coordinate

-14(0) -8 + 7y = 0

7y = 8

y = 7/8

You can get the slope of the line using rise/run which means:

(7/8) / (-7/4)

7/8 x (-4/7)

-28 / 56

m = -1/2

Line 2x-y+1 has a slope of 2.

None of the choices give us an equation with a slope of 2.

The equation -14x-8+7y=0 gives us a slope of -1/2, thus, it is PERPENDICULAR TO THE LINE 2x-y+1=0

I’m not some math genius so then again, I could be wrong…

Hello. Please don’t be offended. I just want to clear something here.

the equations are kx – 8 + 7y = 0 and 2x – y +1 = 0

We are taught that you can just transpose the equation to get the slope using the form y = mx + b

so the two equations will be y = -kx/7-8/7 and y=2x+1

the slopes of the two equations will be the coefficient of the x

so it will be -k/7 and 2

Since to have a parallel equation the equations should have equal slopes.

So we can just make the equation….

-k/7 = 2

(cross multiplication)

-k = 14

[-k = 14]/-1

so it will be -14.:)

I just want to help.:)

kx-8+7y=0…,m=-k/7

2x-y+1=0….,m=2

2=-k/7

14=-k

k=-14

check:

-14x-8+7y=0…,m=14/7 or 2

2x-y+1=0….,m=2

thats my solution…i THINK its correct

di ga po mali ang sagot sa 13? ang explanation po eh tama na 0.99 ang sagot, pero ang marked as correct eh letter C instead of B ..

sa 29 din po.. diga po un ay:

1 = (1/ days of Mrs.Isagani)x + (1/ days of Mrs.Rosas)x

1 = (1/10)x + (1 / (5/2))x

1 = (1/10)x + (2/5)x

1 = (1/10)x + (4/10)x

1 = (5/10)x

1 = (1/2)x

x = 2

awaiting reply po kung tama.. 😀 .. thanks!

Yan din yung sagot ko kasi diba para mag divide na ang denominator ay fraction, ire-reciprocal siya. So magiging 1 * 2/5 = 2/5. Anyare? Bakit hindi nagrecipocal?

Yung question number 9 explanation doesn’t support question number 9’s correct answer. please check po. mukhang baliktad lang po yung B and C.

question number 8 po pala.

Pingback: UPCAT Review – Your Ultimate Guide

I think there’s something wrong with the answer in Q#18. The rate of Mr. Rosas should be x/(5/2). Simplifying it should be 2x/5.

x/10 + 2x/5 = 1

5x/10=1

5x=10

x=2.

So the time should be 2.

This is also what I got

OMG. This so hard, even basic math I can’t pass, lol. But I got 44/50 in Vocabulary. Being American is a great advantage in taking the UPCAT. lmao. Goodluck to all of us.

Question 14 Explanation:

= 20 + 981/9) – (4+9) = 20 + 9 – 13 = 16

merong mali … ung 981/9 dpat 81 lng.. un lang

Typo error lng yun, yun 981/9) should be (81/9) kaya tama pa rin…
