Question

Vishnu's and Sivai's ages are in the ratio 10:17. 4 years ago, their age ratio were 8:15. What is Vishnu's age after 10 years?​

Answer 1

Let the age of Vishnu and Sivai be x .

10x-4/17x-4=8/15

15(10x-4)=8(17x-4)

150x-60=136x-32

150x-136x=-32+60

14x=28

X=2

Vishnu's age =10x=10*2=20years

Sivai's age =17*2=34years

Vishnu's age after 10years=20+10

= 30years

therefore Vishnu's age after 10years will be 30years.

Hope this will help you .
