Expert Answer
Let the present age of father be x years and sum of ages of his three children be y years.
Five years ago , fathers age was 2 times the sum of ages of his three children.
→ (x - 5) = 2(y - 15)
→ x - 2y= - 25 ... (i)
After 5 years fathers age can be obtained by subtracting 8 from the sum of ages of the three children.
→ (x + 5) = (y +15 - 8)
→ x - y = 2 ... (ii)
Subtracting (ii) from (i), we get
y = 27
Put y = 27 in (ii), we get
x = 29
Therefore the present age of father is 29 years.
