Question

Ravi spent a quarte( 1/5) as ayouth, 1/3 as man ,1/4 as boy and 13 yrs in old age. what us his present age

Answer 1

Hey.

Here is the answer.

Let present age be x

So, spent x/5 as youth + x/3 as man + x/4 as boy + 13 in old = x

or, x/5 + x/3 + x/4 + 13 = x

or, (60x - 12x - 20x - 15x)/60 = 13

or, 13x = 60×13

so, x = 60 years

So, his present age is 60 years.

Thanks.
