Solution

Given, Munnu’s age = x years

(x-2) shows an age which is less than Munnu's age by 2 years. It can be his younger brother's or sister's age.

(x + 4) shows an age which is greater than Munnu's age by 4 years. It can be his elder brother's or sister's age.

(3x + 7) shows an age which is 7 years greater than 3 times Munnu's age. It can be his father's age or uncle's age.
