Find the simple interest for an amount of Rs. 2,500 at 8.25% per annum for the period from 1st March 2018 to 12th May 2018.

Principal (P) = Rs. 2,500
Rate of Interest (R) = 8.25% per annum
Time period = From 1st March 2018 to 12th May 2018

​Simple Interest (SI) = (P × R × T) / 100
Solution:

Total time = 31 + 30 + 12 = 73 days

Time = 73 / 365 = 0.2 years

SI = (2500 × 8.25 × 0.2) / 100
SI = 41.25

Therefore, the simple interest for the given period is Rs. 41.25.

Thus, correct option is (d).
