ATQ,
Let the present age of ‘Aman’ = ‘x’ years According to the question, (x + 3) = 1.8 × (x – 5) Or, x + 3 = 1.8x – 9 Or, x = 12 ÷ 0.8 = 15 Sum of present ages of ‘Aman’ and ‘Bishnu’ = 21 × 2 = 42 years So, present age of ‘Bishnu’ = 42 – 15 = 27 years So, required ratio = (15 + 1):(27 + 1) = 16:28 = 4:7
