Question
Present age of βMβ is 25% more than that of βNβ.
4 years ago, βMβ was 1.5 times as old as βNβ. What is the present age of βNβ?Solution
Let the present age of βNβ be βxβ years
Therefore, present age of βMβ = 1.25x years
ATQ;
(1.25x β 4) = 1.5 Γ (x β 4)
Or, 1.25x β 4 = 1.5x β 6
Or, 2 = 0.25x
Or, x = 8
Therefore, present age of βNβ = 8 years
