Simple Interest and Compound Interest

Find the compound interest and amount on $₹50,000$ for $1$ year at the rate of $10\%$ p.a. compounded half-yearly.

$5$ years are equal to $15$ quarter years.

$3$ years are equal to $6$ half years.

Interest is paid when a person takes loan.

Amount is the difference between the principal and the interest.

$\mathrm{CI}=P{\left(1+\frac{R}{100}\right)}^T$

If time is more than $1$ year, then simple interest is less than compound interest.

Simple interest can be equal to compound interest.

$CI=P[$ _____ $-1]$
