Question

Rahim is 15 years older than vimal. ten years ago vimal was half the age of rahim. what is rahims present age?

Answer 1

Let, Age of Vimal=x

then Age of Rahim=(x+15)

Before ten years,

2(X-10)=X+15-10

2X-20=X+5

X=25

So, present age of Rahim is (X+15)=25+15= 40 YEARS.

Did you understand or not??

Answer 2

let age of vimal be x years
age of rahim=x+15 years
ten years ago,
vimal's age =x-10 years
rahim's age=x+15-10
                  =x+5 years
x-10=(x+5)/2
⇒2x-20=x+5
⇒x=25

rahim's age=x+15
                  =25+15
                  =40 years
