# Compute the Amount and the Compound Interest In the Following by Using the Formulae When: Principal = Rs 10000, Rate 20% per Annum Compounded Half-yearly, Time = 2 Years - Mathematics

Sum

Compute the amount and the compound interest in  the following by using the formulae when:
Principal = Rs 10000, Rate 20% per annum compounded half-yearly, Time = 2 years

#### Solution

$\text{ Applying the rule A = P }\left( 1 + \frac{R}{100} \right)^n \text{ on the given situations, we get: }$
$A = 10, 000 \left( 1 + \frac{20}{200} \right)^4$
$= 10, 000 \left( 1 . 1 \right)^4$
= Rs 14, 641
Now,
CI = A - P
= Rs 14, 641 - Rs 10, 000
= Rs 4, 641
