Question
Present age of ‘D’ is 45% more than that of ‘E’.
9 years ago, ‘D’ was 1.75 times as old as ‘E’. Find the present age of ‘E’.Solution
Let the present age of ‘E’ be ‘x’ years
Therefore, present age of ‘D’ = 1.45x years
ATQ;
(1.45x – 9) = 1.75 × (x – 9)
Or, 1.45x – 9 = 1.75x – 15.75
Or, 6.75 = 0.3x
Or, x = 22.5
Therefore, present age of ‘E’ = 22.5 years
