Question

Calculate CI on, a sum of 6,500 for 2years at 6% per annum if the interest is compounded
semi-annually​

Answer 1

SOLUTION

$c.i. = 6500(1 + \frac{6}{100} ) {}^{2} - 6500 \\ = > ci = 6500( (\frac{106}{100} ) {}^{2} - 1 {}^{2} ) \\ = > ci = 6500( \frac{106}{100} + 1)( \frac{106}{100} - 1) \\ = > ci = 6500 \times \frac{206}{100} \times \frac{6}{100} \\ = > ci = 803.4 \: \: rs$

Answer 2

A =p(I +r / 2oo) 2n =

6500 (I +3/100)^4

= 7316

CI = 7316-6500 = Rs 816. Ans.
