Let the age of Kiran at Present be x years. 

Then Rakesh’s present age is (x - 24) years 

10 years ago, the age of Kiran = (x - 10) years and the age of Rakesh = (x - 24 - 10) or (x - 34)years 

According to the question, 10 years ago, Kiran’s age is equal to 5 times the age of Rakesh 

∴ x10=5(x34) 

x10=5x170 

x5x=170+10 

4x=160 

x= 1604 

x=40 

Hence, Kiran’s age = x = 40 years 

Rakesh’s  age = x - 24 = 40 - 24 = 16 years.
