A lends Rs. 2500 to B and a certain to C at the same time at 7% p.a. simple interest. If after 4 years, A altogether receives Rs. 1120 as interest from B and C, then the sum lent to C is? Choose the most appropriate option.
A) 2998	B) 1500	C) 2878	D) 299	E) 277
Let the sum lent to C be Rs. x. Then,   (2500 * 7 * 4) / 100 + (x * 7 * 4) / 100 = 1120   7/25 x = (1120 - 700) =&gt; x = 1500   Answer: 1500
