Question

After 17 years, I shall be 3 times as old as I was 5 years ago. Find my age 4 years from now.

Answer 1

Answer:

In this question we have to keep in mind that always let 'x' as present age.

See the attachment for this question

Answer 2

let the present age be x.

then, his age 4yrs from now = x+4

After 17yrs

his age = x+17

5yrs ago

his age = x-5

A/q

x+17 = 3(x-5)

x+17 = 3x-15

3x-x = 17+15

2x = 32

x = $\frac{32}{2}$

x = 16

So, his present age = 16yrs

His age 4yrs from now = 16+4 = 20yrs
