ConceptConept of Compound Interest

#### Question

Calculate the amount and compound interest on Rs 8000 for 1 year at 9% per annum compound half yearly. (You could use the year by year calculation using SI formula to verify)

#### Solution

Principal (P) = Rs 8000

Rate of interest = 9% per annum or  9/2 % per half year

Number of years = 1 year

There will be 2 half years in 1 year.

A = P(1 + R/100)^n

= Rs [8000(1 + 9/200)^2]

= Rs [8000(209/200)^2] =  Rs  8736.20

C.I. = A − P = Rs 8736.20 − Rs 8000 = Rs 736.20

Is there an error in this question or solution?
