Answer 2

Hi.

Here is your answer---

_____________________

Given---

Simple Interest(S.I.) = Rs. 113.75
             Principal(P) = Rs. 728
                Time(t) = 2.5 years.

For Rate of Interest,

 Using the Formula,
 
                 S.I. = (P × R × T) ÷ 100
          113.75  = (728 × R × 2.5) ÷ 100
728 × R × 2.5 = 113.75 × 100
 Thus, R = 6.25%

Thus, Rate of Interest is 6.25%.
