Question

what Sum will amount to Rs. 6525 at 10% per annum.
compounded yearly for 13 years?
a) Rs. 2889
c) RS. 3889 d) Rs. 1089
b) Rs 1889​

Answer 1

Answer

Let the principal be P

S.I=A−P

=5525−P

Amount=5525Rs

Rate=10%

Time=3 years

S.I.=

100

PRT

5525−P=P×10×

100

3

5525−P=

100

30P

552500−100P=30P

552500=130P

P=

130

552500

P=4250

The sum is 4250.

Answer 2

Answer:

option B

Step-by-step explanation:

CI = A - P

CI is compound interest

A is amount

P is principle

given,

A = P(1+i)^n

P = A\[(1+i)^n]

i is rate of interest in decimal

n is number of years

P = 6525/[(1+i)^13]

P = 6525/3.4522

P = 1890. 099 ~ 1889
