Present ages of Solomon and Arnald are in the ratio of 5:4 respectively. Three years hence, the ratio of their ages will become 11:9 respectively. What is Arnald present age in years?
Answer/Solution
A)24
Steps/Work
Let the present ages of Solomon and Arnald be 5x and 4x years respectively.
Then, (5x + 3)/(4x + 3) = 11/9
9(5x + 3) = 11(4x + 3) => x = 6
Arnald present age = 4x = 24 years.
