Expert Answer:

Let the sum of the ages of 2 children is = x years

Father's age = 3x

after 5 years the sum of the ages of his 2 childern will be = x + 10            (5 year for both the children sums up to 10)

Father's age after 5 years = 2(x+10)

according to the problem :

3x + 5 = 2(x+10)

3x + 5 = 2x + 20

x = 15

Therefore age of the father is = 3 x 15 = 45 years
