Question

find the compound interest on rupees 1000 at the rate of 20% per annum for 18 months when the interest is compounded half yearly ​

Answer 1

Step-by-step explanation:

before finding C.I we have to find amount.

so let's start.

Principal = 1000

Rate = 20%

Time = 18 months

Amount = Principal(1 + Rate/100)×Time

Amount =. 1000(1 + 10%/100)×36 months means 3 year

Amount = 1000×11/10×11/10+×11/10

So Amount = 1331

Now we will find compound interest

formula of compound interest = Amount - Principal

= 1331 - 1000

= ₹331

So Compound Interest = ₹ 331
