Question
A certain sum of money becomes 5000 in 6 years and Rs.
6240 in 10 years at any certain rate of simple interest. Find the principal amount.Solution
Simple interest for 4 years = 6240 – 5000 = Rs.1240 Simple interest for 1 year = 1240/4 = Rs. 310 Simple interest for 6 years = 310 × 6 = Rs. 1860 So, required principal amount = 5000 – 1860 = Rs. 3140
