**Answers and Solution:**

1.A) Let the present age of son be x years.

Then, the present age of father = 5x years.

3 years ago, Son’s age = (x -3) years Father’s
age = (5x – 3) years

But 3 years ago the father’s age was 8 times
that of his son.

Therefore, we can write.

8 (x -3) = 5x -3 or, 8x - 24 = 5x -3 or, 3x = 21

or, x = 7 years and 5x = 35

We get the present age of son = 7 years

**and the present age of father = 35 years**

2.D) Let the present age of B be x years. Then, the
present age of A = 9x years

3 years hence, = B’s age = (9x + 3) years.

But it is given that 3 years hence A’s age
will be 5 times the age of B.

so 9x + 3 = 5(x + 3 ) Or, 9x + 3 = 5x + 15 Or,
4x = 12 Or, x =3

B’s present age = 3 years

**A’s present age = 9 * 3 = 27 years**

3.C)

4.D)

5.D) Let the present ages of father and son be 5x
and 2x years respectively.

According to the question.

=> 5x + 2x = 2 * 35

=> 7x = 70

=> X = 70/7 = 10

**so son's age = 2x = 2 x 10 = 20**

6.C) Let the present ages of Aarzoo and Arnav
be 11x and 13x years respectively,

According to the question,

=> (11x+7)/(13x+7)=20/23 => 260x + 140
= 253x + 161

=> 260x – 253x = 161 – 140 => 7x = 21

=> X = 21/7 = 3 Difference between their
ages

**= 13x – 11x = 2x = 2 * 3 = 6 years**

7.C) Ram : Mohan = 4 : 5 Mohan : Anil = 5 : 6, == Ram : Mohan : Anil = 4 : 5 : 6

**so Mohan’s age = 5/15 * 90 = 30 years**

8.A) Present age of son = x years then father’s
present ages =3x years

According to the question

(3x+4)/(x+4)=13/5 => 15x + 20 = 13x + 52 =
2x = 32

so X = 16

**Present age of father = 3 * 16 = 48 years**
9.A) Let x years ago the radio of their ages
was 3 : 5

so According to the question

(40-x )/(60-x )=3/5

Or, 200 – 5x = 180 – 3x

or, 2x = 20

**so X = 10 years**

10.A)
