Find the age - Problems on Ages Example 1

Rajeev’s Age after 15 years will be 5 times his age 5 years back. What is the present age of Rajeev ?

 

Solution :

               Let Rajeev’s present age be x years. Then

              

               Rajeev’s age after 15 years  =  ( x + 15 ) years.

 

               Rajeev’s age 5 years back = (  x – 5 ) years.

 

               X + 15 = 5 (  x - 5 )

 

               X + 15  =  5x  - 25

 

               4x  = 40

 

               X = 10

 

               Hence, Rajeev’s present age  = 10 years
