The simple interest on a certain sum is 11 \frac{1}{9} % of the sum and the number of years is equal to the rate percent per annum. What will be the simple interest on a sum of ₹ 12600 at the same rate for 2 \frac{4}{5} years?

Solution & Step-by-step Explanation

Given that simple interest is 11 \frac{1}{9} % = \frac{1}{9} of the sum.Let Principal = P, then SI = \frac{P}{9} .Let Rate = R % and Time = T years. Given T = R .Formula: SI = \frac{P \times R \times T}{100} \frac{P}{9} = \frac{P \times R ^{2}}{100} R^{2} = \frac{100}{9} ⟹ R = \frac{100}{3} = 3 \frac{1}{3} % Now, we need to find the simple interest on a sum of ₹ 12600 at the same rate (R = \frac{10}{3} %) for T = 2 \frac{4}{5} = \frac{14}{5} years: SI = \frac{12600 \times \frac{10}{3} \times \frac{14}{5}}{100} SI = 126 \times \frac{10}{3} \times \frac{14}{5} = 126 \times \frac{28}{3} = 42 \times 28 = ₹ 1176
