Question

Rs 62500 for 1 1/2 years at 8% per annum compound half yearly

Answer 1

Principal (P) = Rs 62,500

Rate = 8% per annum or 4% per half year

Number of years = 1 1/2

There will be 3 half years in 1 1/2 years.

A = p(1 + R/100)n = Rs [62500(1 + 4/100)3]

= Rs (62500 x 26/25 x 26/25 x26/25)

= Rs 70304

C.I. = A − P = Rs 70304 − Rs 62500 = Rs 7,804

Answer 2

✨ HEY MATE ✨

➡️Principal for the first half year = ₹62500
➡️Interest for the first half year =
:- 62500*1*4/100 = ₹2500
➡️ Amount at the end of the first half year = ₹(62500+2500) = ₹65000

➡️ Principal for the second half year = ₹65000
➡️ Interest for the second half year =
:- 65000*4*1/100 = ₹2600
➡️ Amount at the end of the second half year = ₹(65000+2600) = ₹67600

➡️ Principal for the third half year = ₹67600
➡️ Interest for the third half year =
:- 67600*4*1/100 = ₹2704
➡️ Amount at the end of the third half year = ₹(67600+2704) = ₹70304

⏭️Amount = ₹70,304
⏭️Compound Interest = Amount - Principal of the 1st year = ₹(70304 - 62500) = ₹7804 ( Answer )
