Question

calculate C.I on 4000 for 3 years at 10% p a​

Answer 1

Answer:

1324rs.

Step by step explanation:

$a = p(1 + \frac{r}{100} )^{3}$

$a = 4000(1 + \frac{10}{100})^{3}$

$a = 4000 \times \frac{11}{10} \times \frac{11}{10} \times \frac{11}{10}$

A = 4×11×11×11

= 4×1331

= 5324 Rs.

Thus,

C.I. = A - P

= 5324 - 4000

= 1324 Rs.
