Find the simple interest (in ₹) on ₹1,200 at an interest rate of 4% per month for 9 months.

Correct option is B

Given:

Principal (P) = ₹1,200

Rate of interest (R) = 4% per month

Time (T) = 9 months

Find the simple interest.

Formula Used:

SI = $$\frac{P \times R \times T}{100}$$​​

Solution:

SI = $$\frac{1200 \times 4 \times 9}{100}$$​​

​$$= \frac{1200 \times 36}{100} \\ \ \\= 12 \times 36 \\ \ \\= ₹432$$​​
