What is the compound interest on a principal of ₹5000 at the rate of 20% for 2 years?
Given:
Principal P=₹ 5000,
Rate of interest, r=20%, and
Time period, n=2 years.
We know thatAmount, A=P[1+r100]n
So, A=5000[1+20100]2=5000 [1210]2=5000×[144100]=50×144=₹ 7200
So Compound interest, C.I. = Amount - Principal
⇒ CI = ₹ 7200−₹ 5000=₹ 2200
