Answer 2

Answer:

20th January 2013 to 10th April 2013=81 days.

Thus, time=81days

Principal=7500

Rate of interest=8%P.A.

$s.i = \frac{p \times r \times t}{100} \\ = \frac{7500 \times 8 \times 81}{100 \times 365} \\ = 133.15 approx \: \\ = amount = principal + s.i \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7500 + 133.15 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7633.15$
