Question

After 32years ,rahim will be 5times as old as he was 8years ago.how old is rahim today

Answer 1

Let Rahim was x years old 8 years back

rahim's age today will be x+8

So rahim's age after 32 years will be x + 8 + 32 = x+40 -----1

And rahim's age after 32 years = 5x -----2

Equating 1 and 2,

x + 40 = 5x

4x = 40

x = 10

Rahim's age today is x+8

= 10+8

18 years

Answer 2

After 32 years, Rahim will be 5 times as old as he was 8 years ago

let present age of Rahim = x

so, after 32 years rahim's age = x + 32......(1)

so, age of Rahim will be 5 times as 8 years ago from present age of x= 5*(x-8) = 5x - 40......(2)

equate (1) and (2)
x + 32 = 5x - 40
5x - x = 32 + 40
4x = 72
x = 18

so, rahim's present age is 18 years
