Question: 1

Find a number such that when 15 is subtracted from 7 times the number, the result is 10 more than twice the number.

(A) 1

(B) 2

(C) 5

(D) 7

Ans: C

Let the number be x.

Then, 7x - 15 = 2x + 10 ⇒ 5x = 25 ⇒ x = 5.

Hence, the required number is 5

.

Question: 2

A number when multiplied by 13 is increased by 180. The number is

(A) 5

(B) 12

(C) 13

(D) 15

Ans: D

Let the number be x.

Then, 13x = x + 180

⇔ 12x = 180

⇔ x = $${180}/{12}$$ = 15.

Question: 3

One third of a two digit number exceeds one fourth of its successive number by 1.

(A) 12

(B) 13

(C) 15

(D) 18

Ans: C

Let the number be x.

Then, $${x}/{3} - {(x + 1)}/{4}$$ = 1

⇔ 4x - 3(x + 1) = 12

⇔ x = 15.

Question: 4

The sum of two numbers is 40 and their difference is 4. The ratio of the numbers is

(A) 11 : 9

(B) 11 : 18

(C) 21 : 19

(D) 22 : 9

Ans: A

Let the numbers be x and y.

Then, $${x + y} / {x – y}$$ = $${40}/{4}$$ = 10

⇔ (x + y) = 10(x – y)

⇔ 9x = 11 y

⇔ $${x}/{y}$$ = $${11}/{9}$$.

Question: 5

Three times the first of three consecutive odd integers is 3 more than twice the third. The third integer is

(A) 9

(B) 15

(C) 18

(D) 24

Ans: B

Let the three integers be x, x + 2 and x + 4.

Then, 3x = 2(x + 4) + 3 ⇔ x = 11.

∴ Third integer = x + 4 = 15.
