Let Asha's present age=x
let Nirmal's present age = y
therefore, x:y = 5:6
let common multiple be k
then, x=5k and y=6k

and, asha's age 5 years from now = x+5
Nirmal's age 5 years from now= y+5
therefore, (x+5):(y+5)= 6:7
5k+5 / 6k+5 = 6/7
or, 35k+35= 36k+30
or, k=5

therefore, present age of Asha=25
and Nirmal= 30
