Present age of Samad and Akmal are in the ratio of 5:4 respectively. Three years later, the ratio of their ages will become 11:9 respectively. What is Akmals present age? Correct Answer 24
Let their present ages be 5x and 4x respectively. Three years later, (5x + 3) : (4x + 3) = 11 : 9 or, (5x + 3) / (4x + 3) = 11/9 or, 9(5x + 3) = 11(4x + 3) or, 45x + 27 = 44x + 33 or, 45x - 44x = 33 - 27 or, x = 6 So, present age of Akmal = 4x = 4×6 = 24 years
