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 6 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 × 6)/100} = x - 450 => 0.6x = - 450 => 0.4x = 450 => x = 450/0.4 = 1125 Therefore, simple interest received = x - 450 = 1125 - 450 = Rs. 675
