Answer 2

let the present age of aleena = 4x present age of alesha = 5x

5 yrs later, age of aleena= 4x+5 age of alesha= 5x+5

that is 4x+5/5x+5 = 5/6

=6(4x+5) = 5(5x+5)

=24x+30 = 25x + 25

=24x-25x = 25 -30

= -1x = -5

= x= -5/-1

= x= 5

therefore

present age of aleena= 4x= 4*5=20yrs present age of alesha = 5x=5*5=25yrs
