1. Step-by-step explanation:

   Given :–

   Present age of Mohan is five times the present age of his son. After 7 years Mohans age will be three times the then age of his son.

   To find:–

   Find the Sum of present ages of Mohan and his Son?

   Solution :–

   Let the present age of Mohan’s son be X years

   Then the present age of Mohan =

   5 times the age of his son

   = 5X years

   After 7 years their ages will be (X+7) and (5X+7)

   After 7 years Mohans age will be three times the then age of his son.

   => (5X+7) = 3(X+7)

   => 5X+7 = 3X+21

   => 5X-3X = 21-7

   =>>2X = 14

   => X = 14/2

   => X = 7 years

   His son age = 7 years

   Mohan’s age = 5X = 5(7) = 35 years

   Their sum = 7+35 = 42 years

   Answer:–

   The present age of Mohan = 35 years

   The present age of Mohan’s son’s age = 7 years

   The sum of their ages = 42 years

   Check :–

   Son’s age = 7 years

   Mohan’s age = 35 years

   => 5×7

   => 5 times his son

   and

   After 7 years their ages 14 and 42

   => 42 = 3×14.

   =>After 7 years Mohans age will be three times the then age of his son.
