Answer 1

Answer:

Rs.1809.84

Step-by-step explanation:

When compounded quarterly, the Rate becomes one-fourth and the Time is multiplied by 4.

Principal (P) = Rs.35750

Rate (R) = (10/4)% per annum

Time (n) = 1/2 × 4 years = 2 years

Amount (A) = P (1 + R/100)ⁿ

=> A = 35750 (1 + 10/400)²

=> A = 35750 × 41/40 × 41/40

=> A = Rs.37559.84

Compound Interest = A-P = Rs.(37559.84 - 35750) = Rs.1809.84

Answer 2

₹1809.84 is the right answer

hope it helps you
