Question
Present age of ‘M’ is 25% more than that of ‘N’.
5 years ago, ‘M’ was 1.5 times as old as ‘N’. Find the present age of ‘N’.Solution
Let the present age of ‘N’ be ‘x’ years
Therefore, present age of ‘M’ = 1.25x years
ATQ;
(1.25x – 5) = 1.5 × (x – 5)
Or, 1.25x – 5 = 1.5x – 7.5
Or, 2.5 = 0.25x
Or, x = 10
Therefore, present age of ‘N’ = 10 years
