An amount of Rs. 75000 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 3/4 %, then the amount invested in each share was? Choose the correct choice from the following choices.
A) s. 46875; Rs. 28125	B) s. 62500; Rs. 37500	C) s. 72500; Rs. 27500	D) s. 82500; Rs. 17500	E) s. 72500; Rs. 17500
Let the sum invested at 9% be Rs. x and that invested at 11% be Rs. (75000 - x). Then,   (x * 9 * 1)/100 + [(75000 - x) * 11 * 1]/100 = (75000 * 39/4 * 1/100)   (9x + 825000 - 11x)/100 = 39000/4 = 14625/2   x = 46875   Sum invested at 9% = Rs. 46875   Sum invested at 11% = Rs. (75000 - 46875) = Rs. 28125.   s. 46875; Rs. 28125NSWER:s. 46875; Rs. 28125
