Question
The simple interest received on a certain sum is Rs.
5500 less than the sum invested. If the sum was invested at 10% p.a. for 9 years, then find the simple interest received.Solution
Let the sum invested be Rs. x Therefore, simple interest received = Rs. (x – 5500) According to the question, {(x × 10 × 9)/100} = x – 5500 => 0.9x = x – 5500 => 0.1x = 5500 => x = 5500/0.1 = 55000 Therefore, simple interest received = x – 5500 = 55000– 5500 = Rs. 49500
