Question

Shravan is 10 years older than Gaurav. Five years ago, one - seventh of Shravan's age was equal to one - fifth of Gaurav's age. Find their present ages.

Answer 1

Let Gaurav's age be x
then Shravan's age is x+10
Five year ago:
Gaurav's age = x-5
Shravan's age = x+5
(x+5)/7=(x-5)/5
cross multiplication
5(x+5)=(x-5)
5x+25=7x-35
25+35=2x
60=2x
30=x
Answer
Gaurav's Age =30
Shravan's Age =40
