Answer 2

Answer:

25 Rs

Step-by-step explanation:

Principal = 10000 Rs

Rate = 10% p.a.

Time = 1 year

Interest = (principal*Rate*time) ÷100

Interest = (10000*10*1)÷100

int. = 1000 Rs

If compounded half yearly

principal (p) =10000 Rs

rate (r) = 10÷2 = 5% (half yearly)

time (n) = 1 year

Compound Interest =

$c.i. = p \times ({(1 - \frac{r}{100} )}^{2n} - 1)$

$c.i. = 10000(( { 1 - \frac{5}{100}) }^{2 \times 1} - 1 ) \\ = 10000(( {1 - \frac{1}{20} })^{2} - 1) \\ = 1025$

compound Interest = 1025

Difference between both interests = (1025 - 1000) = 25

so, Compound Interest on the sum is 25 Rs more than the simple interest.
