Mr Sridharan invested money in two schemes A and B,offering compound interest @ 8 p.c.p.a. and 9 p.c.p.a.respectively. If the total amount of interest accured through the two schemes together in two years was 4818.30 and the total amount invested was 27,000, what was the amount invested in Scheme A?	Choose the correct choice from the following choices.
A) 15,000
B) 13,500
C) 12,000
D) Cannot be determined
E) None of these
Let, in scheme A, Sridharan invest x.   Then, his investment in scheme B = (27000 – x).   Now,   x(1+8100)2+(2700−x)(1+9100)2   – 27000 = 4818.30   or, x(1.08)2 + (27000 – x)(1.09)2 = 31818.30   or, 1.1664x + 32078.7 – 1.1881x = 31818.30   or, 0.0217x = 260.4   or, x = 260.4⁄0.0217 = 12000   Answer 12,000
