Question
The current age ratio of Aman to Bhanu is 4:1. In six
years, Aman’s age will be three times Bhanu’s age at that time. What is Aman’s present age?Solution
ATQ;
Let the present age of ‘Bhanu’ = ‘x’ years
Present age of ‘Aman’ = ‘4x’ years
ATQ;
4x + 6 = 3 × (x + 6)
Or, 4x + 6 = 3x + 18
Or, x = 12
So, present age of ‘Aman’ = 4 × x = 4 × 12 = 48 years
