respectively. After 6 years, their ages will be in the ratio 4:5. What is Aman’s present age?Solution
ATQ,
Let present age of Aman and Arjun is ‘3x’ years and ‘4x’ years, respectively.
According to the question,
(3x + 6)/(4x + 6) = 4/5
Or, 5(3x + 6) = 4(4x + 6)
Or, 15x + 30 = 16x + 24
Or, x = 6
Present age of Aman = 3 × 6 = 18 years
