Answer 2

Answer:

1951

Step-by-step explanation:

Principal (p) = Rs 15625 Rate (r) = 16% per annum = 16/4 = 4% (quarterly) Time (t) = 9 months = 9/12 ×4 = 3quarters of a year By using the formula, A = P (1 + R/100) n = 15625 (1 + 4/100)3 = 15625 (104/100)3 = Rs 17576 ∴ CI = Rs 17576 – 15625 = Rs 1951
