Question
The simple interest received on a certain sum is Rs. 450
less than the sum invested. If the sum was invested at 10% p.a. for 5 years, then find the simple interest received.Solution
Let the sum invested be Rs. x Therefore, simple interest received = Rs. (x – 450) According to the question, {(x × 10 × 5)/100} = x – 450 => 0.5x = x – 450 => 0.5x = 450 => x = 450/0.5 = 900 Therefore, simple interest received = x – 450 = 900 – 450 = Rs. 450
