Rahul age is three time of his son age .five year ago he was four times his son age.find the present age

Answer»

Answer:

45 year and 15 year

Step-by-step EXPLANATION:

Let the present age of his son be 'a'. So his age should be 3 times of a i.e. 3a.

Five year ago:

Age of RAHUL = 3a - 5

Age of his son = a - 5

That time, he was four times of his son's age:

= > 3a - 5 = 4(a - 5)

= > 3a - 5 = 4a - 20

= > 20 - 5 = 4a - 3a

= > 15 = a

So, present age of :

Rahul = 3a = 3(15) = 45 year

His son = a = 15 year
