Solution

Ratio of the present ages of Anjali and Ashu is =2:3
Let age of Anjali =2x
and age of Ashu =3x
5 years hence,
Age of Anjali =2x+5
and age of Ashu =3x+5

According to question,
Ratio of Anjali and Ashu after five years =3:4
2x+53x+5=34
4(2x+5)=3(3x+5)
8x+20=9x+15
9x8x=2015
x=5

Present ages of Anjali =2x=2×5=10 years
and age of Ashu =3x=3×5=15 years
