Answer:
Rs 525
Step-by-step explanation:
So it sounds like the amount is just going to go up by 5%, if it is 5% every amount of time let me know.
Anyway, if anything increases by 5% it is basically saying 500 + 500*.05. 500 of course is just this amount, it can be any value though. This can also be simplified to 500(1+.05) = 500*1.05
So in two years it looks like he has to pay 500*1.05 = 525
