Find the simple interest (in Rs.) on Rs. 4,000 at 7.5% per annum rate of interest deposited on 3 February 2024 and withdrawn on 4 April 2024.

Correct option is C

Given:

Principal P = Rs. 4,000
Rate R = 7.5% p.a.
Period: 3 Feb 2024 to 4 Apr 2024 = 61 days (2024 is a leap year 366 days)

Formula Used:
Simple Interest  $$\text{SI} = \dfrac{P \times R \times T}{100}$$​​

Solution:
T$$=\frac{61}{366}=\frac{1}{6}$$​​
​$$\text{SI}=\frac{4000 \times 7.5 \times \frac{1}{6}}{100}$$​​

​$$=\frac{4000 \times 7.5}{600}$$​​
=50
Simple Interest = Rs. 50
