Q. The compound interest on 5000 Rs. for 3 years at 10% per annum will amount to :
Answer: 1655 Rs.
Notes: $latex \because CI = p\left [ \left ( 1+\frac{R}{100} \right )^{T}-1 \right ]&s=1$ $latex = 5000\left [ \left ( 1+\frac{10}{100} \right )^{3}-1 \right ]&s=1$ $latex = 5000\left [ \left ( \frac{11}{10} \right )^{3}-1 \right ]&s=1$ $latex => CI = \frac{5000\times 331}{1000} = 1655\ Rs.&s=1$ Hence option [D] is correct answer.
