Question

Calculate the compound interest on 9000 in 2years when the rate of inyerest for successive years are 10% and 12%

Answer 1

Answer:

₹ 2088 CI

Step-by-step explanation:

A=P(1+R/100)ⁿ

A=9000 X 110/100 X 112/100     [ P(1+10/100)(1+12/100)]

A=11088

CI=11088-9000=₹ 2088

Answer 2

The compound interest is Rs. 2880.

Step-by-step explanation:

Since we have given that

Sum = Rs. 9000

Time = 2 years

Successive rates = 10% and 12%.

According to question, we get that

$A=9000(1+\dfrac{10}{100})(1+\dfrac{12}{100})\\\\A=9000\times 1.1\times 1.2\\\\A=11880$

So, Compound interest = A - P

= 11880 - 9000

=Rs. 2880

Hence, the compound interest is Rs. 2880.
