Present age of ‘A’ = ‘x – 20’ years Present age of ‘B’ = x – 20 + 8 = ‘x – 12’ years So, 1.25 × (x – 20 + 8) = x + 8 => 1.25 (x – 12) = x + 8 =>1.25x – 15 = x + 8 => 0.25x = 23 => x = 92 Present age of ‘B’ = 92 – 12 = 80 years Present age of ‘D’ = 60 × 2 – 72 = 48 years Desired ratio = (80 – 10):(48 – 10) = 70:38 = 35:19
