What is the rate of interest if the simple interest earned on a certain sum for the 3rd year is Rs. 1,750 and compound interest earned for 2 years is Rs. 3622.5?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 7
SI for 3rd year = SI for 1st year = Rs 1750
CI for 2nd year = 3622.5 - 1750 = Rs 1872.5
Rate of interest = (1872.5 - 1750/1750) × 100 = 7%
