Question

What would be the compound interest obtained on an amount of rs 12500 at the rate of 6 % per annum after 4 yr?

Answer 1

Heya user
Here is your answer !!

Principal = Rs 12500
Rate = 6% p.a.
Time = 4 yrs .

So , Amount = Rs 12500 ( 1 + 6/100 )^4
= Rs 12500 * 53/50 * 53/50 * 53/50 * 53/50
= Rs 5 * 53^4 *1/50 * 1/50
= Rs 15,780 .

So ,CI earned = Rs 3280 (Ans)

Hope it helps !!

Answer 2

C = P(1+r/100)^n
= 12500(1+6/100)^4
= 53^4/ 500
= 15780
C.I obtained = 15780-12500
= 3280
