Let the present age of hari be $\bold{\red{x}}$

then Arjun is thrice of hari's age ,then present age of Arjun to be $\bold{\red{3x}}$

According to the Question:-

After 5 years Arjun will be 2 times of hari's age then their future ages will be -->>

$⇛3x + 5 = 2(x + 5)$

$⇛3x + 5 = 2x + 10$

$⇛3x - 2x = 10 - 5$

$⇛ = 5$

Hence, present age of hari is $\bold{\red{5 }}$years.
