Question
The present age of Aman is two times more than that of
Rakesh. 5 years hence from now, the age of Aman will be twice the age of Suresh at that time. If Rakesh is 5 years younger than Suresh, then find the present age of Aman.Solution
Let the present age of Rakesh be βxβ years Therefore, present age of Aman = x + 2x = β3xβ years Let, present age of Suresh be βyβ years Given, y β x = 5 Or, x = y β 5 Also, (3x + 5) = 2 Γ (y + 5) Or, 3 Γ (y β 5) + 5 = 2y + 10 Or, 3y β 15 + 5 = 2y + 10 Or, y = 20 Therefore, x = y β 5 = 15 Therefore, present age of Aman = 3x = 3 Γ 15 = 45 years
