Question

the ages of bhanu and indu are in the ratio 3:5 after 10 years the ratio of their ages will be 11:15 find the present age of indu

Answer 1

Step-by-step explanation:

Let the present age of indu5x and Bhanu 3x

after 10year , age of indu 5x+10

and age of Bhanu 3x+10

3x+10:5x+10= 11:15

3x+10/5x+10=11/15

on cross multiplying

15(3x+10)=11(5x+10)

45x+150=55x+110

45x-55x=110-150

-10x=-40

x=40/10

x=4

Hence present age of indu

=5x=20yr

and age of Kavita

3x=12yr
