Answer 2

Let the age of Father be = x

Let the sum of ages of 5 children be = Y

After 15 years the father age be = ( X + 15 )

The sum of ages of 5 child's be = ( Y + 15 × 5). =

( Y + 75 )

According to the question

X = Y

Y + 75 = 2( X + 15)

Y + 75 = 2x + 30

Y + 75 = 2x + 30 using equation 1

75 - 30 = 2x - x

X = 45

The age of Father is = 45
