Math Aptitude Test For Your Mathematical Skills...

...hence each job requires a specific mathematical knowledge and offers a unique math aptitude test.

When you are applying for the situation of a computer programmer, you need not be very good at math. However, when you are going for a post of a civil engineer you can’t afford bad scoring.

On the other hand almost all of the employer organizations use math aptitude test for screening purposes in one way or the other. They may be different in subjects but most of them include questions upon the following areas:

• Algebra

• Quadratic Equations

• Probability

• Trigonometry

• Number series

• Statistics

• Permutations and Combinations

• Profit and Loss

• Geometry

Sample Math Aptitude Questions

This is not a professionally built mathematical test but a simple effort to exemplify it. These sample questions will help you to know general style of math aptitude tests. Foe Example...

The L.C.M. (Lowest (or Least) Common Multiple) of two numbers is 45 times to their H.C.F (Highest Common Factor). If one of the numbers is 125 and sum of L.C.M. and H.C.F. is

1150, the other number is:

a) 215

b) 220

c) 225

d) 235

Solution: Let L.C.M. be l and H.C.F. be h. Then l = 45h

l + h =1150

This gives h =25 and l = 1125

Thus the second number = (25 * 1125)/125 = 225

Mathematical Aptitude Test Question 2

a) 4

b) 10

c) 15

d) 16

Solution: L.C.M. of 2,4,6,8,10,12 = 120

So they toll together after every 120 seconds i.e. 2 minutes. So in 30 minutes they toll together 30/2 + 1 = 16 times

Math Aptitude Test Question 3

a) 0.3825

b) 3.825

c) 38.25

d) 382.5

Solution: The sum of decimal places in numerator and denominator being the same, decimal point can be removed

(625*729*289) / (17*25*81) = 3825

Algebra Aptitude Test Question 4

Find x if sin(x+36^) = cos x

Solution:

sin(x+36^) = cos x

cos(90^ - (x+36^)) = cos x

90^ - (x+36^) = x

2x = 54^

x= 27^

Math Aptitude Test Question 5

I am three times as old as my son. Five years later I shall be two and a half times as old as my son. What is my age?

Solution:

Let my age be x years and age of my son be y years.

(i) x = 3y

Five years later

(ii) x+5 = 5/2(y+5)

From (i) and (ii)

y=15 and x=45

Math Aptitude Test Question 6

The number of coins 1.5 cm in diameter and 0.2cm thick to be melted to form a right circular cylinder of height 10 cm and diameter 4.5 cm is:

a) 380

b) 450

c) 472

d) 540

Solution: Volume of 1 coin = 22/7 *(1.5)/2*(1.5)/2 * 0.2 = 99/280 cm3

Volume of large cylinder = 22/7 *(4.5)/2*(4.5)/2 * 10 = (99*45)/28cm3

Number of coins = (99*45)/28 * 280/99 = 450

Math Aptitude Test Question 7

a) 6

b) 8

c) 12

d) 16

Solution: Size of each cube = 5 cm

So number of blocks = (5 * 10 * 20)/(5*5*5) = 8

Numerical Aptitude Test Question 8

a) 510

b) 242

c) 106

d) 46

Solution:

2nd term = (Ist term - 30) / 2 = (1050-30)/2 = 510

3rd term = (2nd term - 26) / 2 = (510-26)/2 = 242

4th term = (3rd term - 22) / 2 = (242-22)/2 = 110

So 106 is the answer.
