Monica Capoor Solutions for Chapter: Comparing Quantities III Compound Interest, Exercise 3: EXERCISE

Abhimanyu invested $₹100000$ at $13\%$ p.a. compounded annually. Find the following

The amount standing to his credit at the end of the second year.

A man borrows $₹1000$ at $10\%$ p.a simple interest for $3$ years. He immediately lends this money out at compound interest at the same rate for the same time. What is his gain at the end of $3$ years.

Which will earn more interest and how much?

$₹6000$ lent at $12\%$ p.a. compounded annually for $1\frac{1}{2}$ years.
$₹6000$ lent at $12\%$ p.a. compounded half yearly for $1\frac{1}{2}$ years.

If the difference between the compound interest and simple interest for $2$ years at $12\%$ p.a. compounded annually is $₹108$, find the sum borrowed.

Find the principal if the compound interest at the rate of $5\%$ per annum compounded annually for $3$ years is $₹1261$.

At what rate per cent per annum will $₹625$ amount to $₹676$ in $2$ years when compounded annually.

In how many years will $₹4000$ amount to $₹4630.50$ at $5\%$ per annum, compounded annually ?

A sum compounded annually becomes $\frac{25}{16}$ times of itself in $2$ year. Determine the rate of interest per annum.
