Explanation

Given ages ratio 5:9 with difference 40 years. Let ages be 5x and 9x. Then 9x - 5x = 40, so 4x = 40, x = 10. Ages are 50 and 90. The question asks for sum of ages: 50 + 90 = 140. Note: The question wording is confusing - it says 'difference is 40' then asks for 'difference' but the answer 140 is the sum.
