Question
10 years ago, the age of βPβ was 50% more than the
age of βQβ. If the sum of their present ages is 75 years, find the present age of βPβ.Solution
Let the present ages of βPβ and βQβ be (x + 10) years and (y + 10) years, respectively. ATQ; x = 1.5 Γ y = 1.5y β¦β¦β¦β¦β¦β¦. (1) Also, x + y = 55 β¦β¦β¦β¦β¦. (2) Putting x = 1.5y from equation (1), we have 1.5y + y = 55 Or, 2.5y = 55 So, y = 22 So, x = 55 β 22 = 33 Therefore, present age of βPβ = 33 + 10 = 43 years
