Question
The simple interest received on a certain sum is Rs. 250
less than the sum invested. If the sum was invested at 15% p.a. for 4 years, then find the simple interest received.Solution
Let the sum invested be Rs. x Therefore, simple interest received = Rs. (x – 250) According to the question, {(x × 15 × 4)/100} = x – 250 => 0.6x = x – 250 => 0.4x = 250 => x = 250/0.4 = 625 Therefore, simple interest received = x – 250 = 625– 250= Rs. 375
