Mr.Govind invested an amount of Rs.13900 divided in two different schemes S1 and S2 at the simple interst rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in two years was Rs.3508, what was the amount invested in Scheme S2? Choose the correct answer:
A) Rs.6400	B) Rs.6500	C) Rs.7200	D) Rs.7500	E) Rs.7800
Let the sum invested in Scheme S1 be Rs.x and that in Scheme S2 be Rs.(13900-x).   Then, (x*14*2)/100 + ((13900-x)*11*2)/100 = 3508;   28x-22x= 3350800-(13900*22);   6x = 45000; x= 7500   So sum invested in Scheme S2 = Rs. (13900-7500) = Rs.6400   Rs.6400NSWER:Rs.6400
