An amount of Rs. 100000 is invested in two types of shares. The first yields an interest of 9% p.a and the second, 11% p.a. If the total interest at the end of one year is 9 1/4 %, then the amount invested at 11% was?	Choose the correct choice from the following:  A) 12500  B) 37500  C) 29977  D) 26777  E) 19871
Let the sum invested at 9% be Rs. x and that invested at 11% be Rs. (100000 - x). Then,   (x * 9 * 1)/100 + [(100000 - x) * 11 * 1]/100 = (100000 * 37/4 * 1/100)   (9x + 1100000 - 11x) = 37000/4 = 925000   x = 87500   Sum invested at 9% = Rs. 87500   Sum invested at 11% = Rs. (100000 - 87500) = Rs. 12500.   12500nswer: 12500
