    Explanation:
    Let the age of Sneha = x,
    her cousin’s age = x – 8,
    Cousin’s mother age = x – 8 + 24
    Ratio between the ages of Sneha and her cousin’s mother is 7 : 11
    x : x + 16 = 7 : 11
    11 × x = (x + 16) × 7
    11x = 7x + 112
    4x = 112
    x = 28
    Sneha’s cousin age = 28 – 8 = 20
    After 3 years Sneha’s cousin age = 20 + 3 = 23 years
