Question

what is the compound interest on Rs 4000 for 9 months at 6% p..a if the interest is calculated quarterly​

Answer 1

The compound interest will be Rs. 1.80

Step-by-step explanation:

Given, Principal = P = Rs. 4000

Time = t = 9 months = $\frac{9}{12}$ years = 0.75 years

Rate of interest = r = 6% = 0.06

n = Number of compounding periods per year = 4 (Compounded quarterly)

A = Amount after t years

C.I = Compound Interest

By using the formula for compound interest,

$A = P ( 1 + \frac{r}{n} )^{nt}$

Plug the values in the formula we get,

=> A = 4000$(1 +\frac{0.06}{4} )^{(4\times .75)}$

=> A = Rs. 4001.80

Compound Interest = C.I = A - P = Rs. 4001.80 - Rs. 4000 = Rs. 1.80

Hence, the compound interest will be Rs. 1.80
