Answer» We know that, FORMULA for SIMPLE interest: $(S.I. = \frac{{P \times R \times T}}{{100}})$ Where, S.I. = Simple Interest P= principal T = Time R = Rate of interest Interest PAYABLE to A = 3500 × (10/100) × 3 = 1050 Interest payable to B = 3500 × (11.5/100) × 3 = 1207.5 The basic amount in both transactions is same. So, difference between interests in two transactions is the gain. ∴ B’s gain = amount B gets – amount B has to pay = 1207.5 – 1050 = 157.5 |
