Question

calculate the amount when p=1000 R=10per annum(compounded annually)time 2 years​

Answer 1

Answer:

Here, Principal P = Rs. 1000 

R =10% per annum and n=2 years

∴ Amount after 2 years = P (1+200R)2n

= Rs. 1000×(1+20010)2×2=Rs.1000×(1+201)4=Rs.1000×(2021)4

= Rs.1000×2021×2021×2021×2021=Rs.1215.50 

Hence, compound interest = Amount - Principal

=Rs.1215.50−Rs.1000=Rs.215.50
