Q. A lends Rs. 2500 to B and certain sum to C at the same time at 7% annual simple interest. If after 4 years, A altogether receives Rs. 1120 as interest from B and C, the sum lent to C is :
Answer: 1500
Notes: Let the sum lent to C be x According to the question, $latex => \frac{2500\times 7\times 4}{100}+\frac{x\times 7\times 4}{100}=1120&s=1$ $latex =>2500\times 28 + 28x = 112000$ $latex => 2500 + x = 4000$ $latex => x = 4000-2500 = 1500$ Hence option [B] is the right answer.
