1. 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?

2.  A. Rs. 6400 B. Rs. 6400 C. Rs. 7200 D. Rs. 7500 E. None of these

Explanation :

Let the sum invested in Scheme A be Rs. x and that in Scheme B be Rs. (13900 - x).

 Then, $$[ \frac { XX 14 *2} { 100 }]$$ +$$[\frac { (13900-X)*11*2 } { 100 }]$$ = 3508

28x - 22x = 350800 - (13900 x 22)

6x = 45000

x = 7500.

So, sum invested in Scheme B = Rs. (13900 - 7500) = Rs. 6400.
