Question
Present age of ‘R’ is 30% more than that of ‘S’. 4
years ago, ‘R’ was 1.6 times as old as ‘S’. Find the present age of ‘S’.Solution
Let the present age of ‘S’ be ‘x’ years
Therefore, present age of ‘R’ = 1.3x years
ATQ;
(1.3x – 4) = 1.6 × (x – 4)
Or, 1.3x – 4 = 1.6x – 6.4
Or, 2.4 = 0.3x
Or, x = 8
Therefore, present age of ‘S’ = 8 years
