Question

Find the difference between CI (compounded half-yearly) and SI on Rs. 10000 for 1.5 years
at the rate of 20% per annum

Answer 1

Answer:

Rs.4280

Step-by-step explanation:

Principal-Rs.10000

Time- 1.5 years or 3/2 years

Rate- 20%

$simple interest=p×r×t÷100$

=(10000 x 20 x 3/2)÷100=3000

Simple interest-Rs 3000

Compound interest(half yearly)

amount- p(1 + r / 200)^2t

Compound interest=Amount -principal

10000(1+20/100)^2*3/2

=17,280

CI=17280-10000=7280

Difference between SI and CI

CI-SI=7280-3000=4280
