Answer 1

Answer:

:hello here is your answer

Step-by-step explanation:

: The annual interest rate is 6.75 %.

Step-by-step explanation:

Since, the simple interest is,

S.I.=\frac{P\times r\times t}{100}S.I.=

100

P×r×t

\implies r = \frac{S.I.\times 100}{P\times t}⟹r=

P×t

S.I.×100

Where, P = principal amount,

r is the annual rate of interest,

t is the time in years,

Here, P = 1600 rupees, t = 2 years 4 months = 7/3 years ( since, 1 year = 12 months, S.I. = 252 rupees,

\implies r = \frac{252\times 100}{1600\times 7/3}⟹r=

1600×7/3

252×100

=\frac{25200\times 3}{11200}=\frac{75600}{11200}=6.75\%=

11200

25200×3

=

11200

75600

=6.75%

Hence, The annual interest rate is 6.75 %
