Question: 1

Find the number which when multiplied by 15 is increased by 196.

(A) 10

(B) 14

(D) 28

Ans: B

Let the number be x.

Then, 15x - x = 196

⇔ 14x = 196 ⇔ x = 14.

Question: 2

The product of two whole numbers is 37. The square root of the difference of the numbers is

(A) 4

(B) 5

(D) 6.5

Ans: C

Let the numbers be a and b.

Then, ab = 37 ⇒ a = 1 and b = 37.

So, $$√b - a$$ = $$√37 - 1$$ = $$√36$$ = 6.

Question: 3

What is the sum of two consecutive even numbers, the difference of whose squares is 84?

(A) 34

(B) 38

(D) 48

Ans: C

Let the numbers be x and x + 2.

Then, (x + 2)² - x² = 84

⇔ 4x + 4 = 84

⇔ 4x = 80

⇔ x = 20.

∴ Required sum = x + (x + 2) = 2x + 2 = 42.

Question: 4

The sum of the digits of a two digit number is 9 less than the number. Which of the following digits is at unit’s place of the number?

(A) 2

(B) 4

(D) data inadequate

Ans: D

Let the ten’s digit be x and unit’s digit be y.

Then, (10x + y) - (x + y) = 9 or x = 1.

From, this data, we cannot find y, the unit’s digit.

So, the data is inadequate.
