-   Let the Principal be P   S.I. = 360   P x 10 x 3  = 360     100       P = 360 x 100  = Rs. 1200   10 x 3  

To solve the problem, we can use the formula for simple interest:

Simple Interest = (P × R × T) / 100

where P is the principal, R is the rate of interest, and T is the time period.

We are given that:

• Srimathy borrowed a sum for 3 years
• The rate of interest is 10%
• The total interest paid was Rs. 360
• Using the formula for simple interest, we can write:

360 = (P × 10 × 3) / 100

Simplifying this equation, we get:

360 = (3P) / 10

Multiplying both sides by 10/3, we get:

P = 1200

Therefore, the principal borrowed by Srimathy was Rs. 1200, which is option C.
