Show answer & explanation
Correct answer: D
Given:
Principal = Rs. 3200
Rate = 20% per annum
Time = 2 years
Formula used:
Compound interest = P[(1 + r/100)^n − 1]
Calculation:
Compute the growth factor: (1 + 20/100)^2 = (1.2)^2 = 1.44
Amount after 2 years = 3200 × 1.44 = 4608
Compound interest = Amount − Principal = 4608 − 3200 = 1408
Answer: The interest received after two years is Rs. 1408.
