41. Present ages of Abi and Suji are in the ratio of 5:4 respectively. Three years hence, the ratio of their ages will become 11:9 respectively. What is Suji's present age in years?
Answer:
Let the present ages Abi and Suji be 5x years and 4x years respectively.
Then, 5x+3 / 4x+3 = 11/9
=> 9(5x+3) = 11(4x+3) => x=6.
Therefore, Suji's present age = 4x = 24 years.
