Find the compound interest on Rs 8000 at 15% per annum for 2 years, componded annualy.
Answer & explanation
Correct answer: option 1
From the formula for compound interest, we know,
C.I = P(1+$\frac{R}{100})^t$– P
Compound Interest on Rs 8000 for 2 years = 8000(1+$\frac{15}{100})^2$– 8000
= 8000($\frac{23}{20})^2$ - 8000
= 8000($\frac{529}{400}$ - 1)
= 8000($\frac{129}{400}$) = Rs 2580.00
