Question
A sum of ₹12,000 is invested at a certain rate of
simple interest for 3 years. If the total interest earned at the end of 3 years is ₹2,160, find the rate of interest per annum.Solution
Using the simple interest formula: SI = (P × R × T) / 100 Where SI = ₹2160, P = ₹12,000, T = 3 years, and R is the rate of interest. 2160 = (12000 × R × 3) / 100 2160 = 360R R = 2160 / 360 R = 6% Correct answer: b) 6%
1231 + 1312 + 2113 – 3211 = ?
