A father's age is three times the sum of the ages of his two children. After 5 years his age will be two times the sum of their ages.Find the present age of the father.
If the sum of the present ages of both children =x.
Then the present age of father = 3x.
After 5 years,
sum of children age = x+5+5=x+10
Father's age = 3x+5
According to the question,
father's age after 5 years = 2(Sum of the ages of both children)
Present age of father = 3x = 3(15) = 45 years.
