Question

Rakesh is now 3 times as old as his little brother Pinku, but in 3 more years he will be only twice as old as Pinku will be then. How old they are now?

Answer 1

Let Pinku present age be x, Rakesh present age = 3x After 3 years, Pinku age = x + 3, Rakesh age  = 3x+ 3 A.T.Q. 3x + 3 = 2 ( x + 3 ) 3x + 3 = 2x + 6 3x - 2x = 6 - 3 x = 3,Pinku Present age = x =  3 , Rakesh Present age   =  3x = 3 * 3 = 9

Answer 2

Answer:

Currently, Pinku is 2 years old and Rakesh is 6 years old.

Step-by-step explanation:

Let us assume Pinku's age to be x

Therefore, Rakesh's age=3x

In two years,

Pinku's age=x+2

Rakesh's age=2(x+2)

Taking ratios we get,

$\frac{x}{3x}=\frac{x+2}{2(x+2)\\}$

∴2x(x+2)=3x(x+2)

∴2x²+4x=3x²+6x

∴x²=2x

∴x=2

Therefore, Pinku is 2 years old and Rakesh is 3*2=6 years old.
