Question

If the SI on a sum of money for 2years at 5% per annum is ₹ 50 what is the CI on the same rate and same time​

Answer 1

Let the sum = P Rs

S.I = 50 Rs

Rate of interest = 5%

Time = 2years

➪ S.I = P × R × T

100

➪ 50 = P × 5 × 5

100

➪ P = 50 × 100 = 500 Rs

5 × 2

C.I of 500 Rs

Amount = 500 ( 1 + 5 )²

100

➪ 500 = 105 × 105

100 100

➪ 500 = 21 × 21

20 20

➪ 551.25

C.I = 551 – 500 – 51.25 Rs
