Question

When anil will become as old as his father is now, he will be four times the present age of his son and then his son will be nine years older than what anil is now. If the sum of his father's age and his age is 80 years old, then how old is anil now?

Answer 1

Solution:

Let present age of Anil = x years

So age of his father = (80-x) years

Age of Anil’s son = (80-x)/4

When Anil will be as old as his father i.e. (80-x) years

So age of Anil’s son = (80-x)/4 + (80-x-x)

Now

(80-x)/4 + (80-2x) = x + 9

This gives age of Anil, x = 28
