Answer 1

Answer:

Step-by-step explanation:

Given that Simple interest. = Rs 5700. Time (T) = 3 years Rate (R) = 4% Principal = ? S.I = ( P.T.R) / 100. 5700 = (P x 3 x 4) / 100. P = ( 5700 x 100) / 12 P = 47500 Rs. Hence, the sum of money is equal to Rs 47500. (ii) Sol: Given that Simple interest. = Rs 13875. Time (T) = 1 year 3 months = 1 + (3 / 12) = 5 / 4 Rate (R) = 9% Principal P = ? S.I = ( P.T.R) / 100. 13875 = (P x (5/4) x 9) / 100. P = ( 13875 x 100 x 4) / 45. P = 5550000/ 45. P = 123334 Rs. Hence, the sum of money is equal to Rs 123334.
