Question

at what rate per cent per annum will rupees 4000 to rupees 4410 in 2 years when compounded annually.
​

Answer 1

Answer:

PRINCIPLE = 4000

AMOUNT = 4410

S.I.= AMOUNT - PRINCIPLE

=410

TIME = 2 Years

Step-by-step explanation:

$rate \: of \: interest = \frac{simple \: interest \: \times 100}{principle \times time }$

$= \frac{410 \times 100}{4000 \times 2} \%$

$= \frac{41}{8} \%$

$5 \times \frac{1}{8} \%$

Answer 2

Answer:

Given that :

Principal amount P =Rs 4000

Number of years N=2 years

Compound interest CI=Rs 410

The formula for compound interest is given by:

CI = A - P

CI = P(1+R/100) n-p

410 = 4000(1+R/100)2-4000

4410=4000(1+R/100)2

4410/4000=(1+R/100)2

441/400=(1+R/100)2

21/20=1+R/100

1/20=R/100

R=5%
