The ages of Shivali and Tanisha are in the ratio of 11 : 7 respectively. After 8 years the ratio of their ages will be 15 : 11. What is thedifference in years between their ages?

Let, the age of Shivali be, S=11x and age of Tanisha be, T=7x.

Now, according to question after 8 years the ratio of their age become 1511.

11x+87x+8=1511

121x+88=105x+120

x=2

Difference in ages =15×211×2

=8 years
