Question

if the simple intrest on a sum of money for 2 years at 5%p.a. annum is Rs.50 what is the compound intrest on the same rate for the same time?​

Answer 1

Answer: SI = Rs. 50     T= 2    R%= 5%

SI = P R T/100

50= P x 5 x 2/100

50 = P/10

500 = P

Now we will find the CI

A = 500(1+5/100)to the power 2

A= 5 x 21 x 21/2 x 2

A= Rs. 551.25

CI = 551.25 - 500

CI = Rs. 51.25

Answer 2

Step-by-step explanation:

Given, S.I = Rs. 50

T= 2 year

Rate = 5%

sum = principal

Therefore, we know. S.I = P•R•T/100

Sum = 50×100/2×5

= Rs. 500

Again , we know. Amount = p(1+R/100)²

A = 500 ( 1+ 5/100 )²

A = 500 ×21/20×21/20

A = Rs. 551.25

Compound Interest = A-P

= Rs. 551.25-500

= Rs. 51.25
