## Raghu’s age after 15 years will be 5 times his age 5 years back. What is the present age of Raghu ?

Let Raghu’s present age be $x$ years. Then,

Raghu’s age after 15 years = ($x$ + 15)  years.

Raghu’s age 5 years back = ($x$ – 5)  years.

($x$+ 15) = 5($x$ – 5)

$x$ + 15 = 5$x$ – 25

4$x$ = 40

$x$ = 10
