At what of interest per year a sum of Rs 7200amount to Rs 9540 in 5 years?​

Answer»

Answer:

difference=9540-7200

=2340

so, weknow that INTEREST =Principal×time×RATE/100

and interest is 2340

so,2340=7200×5×rate/100

we GET, rate=(2340×100)/7200×5

rate=2340/360

rate=6.5

so, at the rate of 6.5%interest PER annum.

hope it helps you dear☺️☺️☺️
