Question

The ages of shakti and kanti are in the ratio of 8:7 respectively. After 10 years the ratio of their ages will be 13:12. What is the difference in years between their ages?

Answer 1

5 years
hope the ansr is correct

Answer 2

age of shakti /age of kanti=8x:7x
after 10yrs=(8x+10)/(7x+10)=13/12
(8x+10)*12=(7x+10)*13
96x+120=91x+130
96x-91x=130-120
5x=10
x=2
shakti =13*2=26
kanti=12*2=24
26-24=2years difference
