Mr. Thomas invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in Scheme B?  Choices
A) 6400 B) 7300 C) 6438 D) 6439 E) 9473
Let the sum invested in Scheme A be Rs. x and that in Scheme B be Rs. (13900 - x).   Then, x x 14 x 2	/100	+ (13900 - x) x 11 x 2	/100	= 3508   28x - 22x = 350800 - (13900 x 22)   6x = 45000   x = 7500.   So, sum invested in Scheme B = Rs. (13900 - 7500) = Rs. 6400.   6400nswer:6400
