Suppose present age of man = 4x years
Present age of his wife
= 3x years
After 4 years

4x+4

3x+4

=

9

7

⇒ 28x + 28 = 27Xx + 36
⇒ 28x - 27x = 36 - 28
∴ x = 8
Present age of man = 4x
= 4 × 8 = 32 years
Present age of his wife = 3x
= 3 × 8 = 24 years
Suppose, they were married y years ago
According to question

32−y

24−y

=

5

3

⇒ 96 - 3y = 120 - 5y
⇒ 5y - 3y = 12 - 96
⇒ 2y = 24
∴ y = 12
