Question

the compound interest on rupees 20000 for 2 years at the rate of 10% per annum is ​

Answer 1

Answer:

Step-by-step explanation:

CI = Principal (1 + r/100)^t - Principal

Its calculated half yearly so rate will get half and time will get doubled

= 20000 (1 + 2/100)^4 - 20000

= 20000 (51/50)^4 - 20000

= 20000 * 51/50 * 51/50 * 51/50 * 51/50 - 20000

= 21648.64 - 20000

= 1648.64

Answer 2

Step-by-step explanation:

compound interest-

P(R+1/100)^T

=20000(1+10/100)^2

=20000(110/100)^2

=22000 RS.

ci= 22000-20000= 2000
