Answer 1

Answer:

5-3 =2 rahul present age is 2 years

Answer 2

Given :

Rahul is twice as old as Haroon.

Five years ago his age was three times of Haroon's age.

To Find :

Present Age of Rahul and Haroon .

Solution :

$\longmapsto\tt{Let\:Present\:age\:of\:Haroon\:be=x}$

As Given that Rahul is twice as old as Haroon. So ,

$\longmapsto\tt{Present\:age\:of\:Rahul=2x}$

Before 5 years :

$\longmapsto\tt{Age\:of\:Haroon=x-5}$

$\longmapsto\tt{Age\:of\:Rahul=2x-5}$

A.T.Q :

$\longmapsto\tt{2x-5=3(x-5)}$

$\longmapsto\tt{2x-5=3x-15}$

$\longmapsto\tt{2x-3x=-15+5}$

$\longmapsto\tt{-x=-10}$

$\longmapsto\tt\bf{x=10}$

Value of x is 10 .

Therefore :

$\longmapsto\tt{Present\:Age\:of\:Haroon=x}$

$\longmapsto\tt\bf{10\:yrs}$

$\longmapsto\tt{Present\:Age\:of\:Rahul=2(10)}$

$\longmapsto\tt\bf{20\:yrs}$
