Explanation:

Let Somya’s father age = x

Somya’s age = x/3

According to the question,

(x − 5) ×
 1 4
=
 x 3
− 5
(x − 5) ×
 1 4
=
 x − 15 3

3x − 15 = 4x − 60

5x − 4x = 60 − 15

x = 45

Explanation:

At the time of marriage let Meenal’s age = x years

According to the question,

(x + 6) = x ×
 7 6

6x + 36 = 7x

x = 36

The present age of Meenal = 36 + 6 = 42

The present age of the daughter = 42/7 = 6

Daughter’s age (2 years ago) = 4 years

Explanation:

Total age of the family of six members = 25 × 6 = 150 years

Total age of the all the family members at the time of the birth of the youngest member = 150 − (12 × 6)

= 150 − 72 = 78

At the time of the birth of the youngest member total member = 6

Average = 78/6 = 13 years

Explanation:

Let the age of Anjali = 7x, Age of Anubhav = 5x

According to the question,

 5x + 10 7x + 10
=
 10 13

13 (5x + 10) = 10 (7x + 10)

65x + 130 = 70x + 100

70x − 65x = 130 − 100

5x = 30

x = 6

Present age of Anjali = 30

Anubhav = 42

Difference = 42 − 30 = 12 years

Explanation:

Let the age of daughter = 2x

The age of woman = 5x

Total age of Daughter and Woman = 56 × 2 = 112

According to the question,

2x + 5x = 112

7x = 112

x = 16

Daughter’s age = 32

Daughter’s age will be 8 years hence = 32 + 8 = 40 years
