The simple interest on Rs. 36000 for the period from 5th January to 31st May, 2013 at 9.5% per annum is = ?

Answer: Option A

Number of days
= 26 + 28 + 31 + 30 + 30 + 31
= 146 days
$$\begin{array}{rl}& \Rightarrow \text{SI = }\frac{\text{P}\times \text{R}\times \text{T}}{100}\\ & \Rightarrow \text{SI = }\frac{36000\times 9.5\times 146}{100}\\ & \Rightarrow \text{SI = Rs}\text{. 1368}\end{array}$$
