Answer:
Step-by-step explanation:
let age of the age of the brother be x, then we have
Age of younger sister = x + 4
Age of girl = x + 4 + 4 = x + 8
ATQ : x + x + 4 = 16
= > 2x + 4 = 16
=> 2x = 12
=> x = 6
Therefore age of brother = x = 6years
Age of younger sister = x + 4 = 10 years
Age of girl = x + 8 = 14 years
