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

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
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
