Detailed Solution
Download Solution PDFLet the ages of the man and his wife be 5x and 8x respectively.
After ten years,
ratio of the man and his wife will be 2 : 3;
⇒ (5x + 10) / (8x + 10) = 2 : 3
Hence, x = 10
The ages of the man and his wife are 50 and 80 respectively.
∴ The ratio of their ages after 20 years is 70 : 100 = 7 : 10
