Question: Find the simple interest on a principal of $140 for a period of 4 years at an interest rate of 3%. Steps to derive 1 Simple interest is the interest paid only on the original deposit or the principal.2 The formula used to calculate the simple interest is I ptr I p t r 3 The rate of interest is 3% = 3 ÷ 100 = 0.03p t r 4 I 5 = 16.806 The simple interest earned on the principal of $140 for a period of 4 years at an interest rate of 3% is $16.80.Hence the right answer is Option B Click Here To Go Back Name the right triangles in the rhombus.(1) ΔABD and ΔBDC(2) ΔAOD and &D..
