Question

12. Ritu is now four times as old as his brother Raju. In 4 years time, her age will be twice
of Raju's age. What are their present ages?​

Answer 1

Answer:

Raju's present age=6 yrs.

Rita's present age=6×4=24 yrs.

Step-step explanation:

Let the present age of Raju be x

Then, the age of Raju after 12 yrs. is 12+x

Then, the present age of Rita is 4x

Then, the age of Rita after 12 yrs. is 12+4x

So,2(12+x)=12+4x

Or,24+2x=12+4x

Or,24-12=4x-2x

Or,12=2x

Or,x=12/2=6

Raju's present age=6 yrs.

Rita's present age=6×4=24 yrs.
