We can say that let the present ages of ‘Anita’ and ‘Sunita’ be ‘3y’ years and ‘4y’ years respectively. ATQ; 4y + 4 = 4y × 1.2 Or, 4y + 4 = 4.8y Or, 4 = 0.8y So, y = 5 So, present age of ‘Sunita’ = 4 × 5 = 20 years Present age of ‘Anita’ = 3 × 5 = 15 years Therefore, ‘Anita’ is (20 – 15) i.e. 5 years younger than ‘Sunita’
