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?
Answer: Option
Explanation:
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 |  |
+ | |
(13900 - x) x 11 x 2 | |
= 3508 |
| 100 | 100 |
28x - 22x = 350800 - (13900 x 22)
6x = 45000
x = 7500.
So, sum invested in Scheme B = Rs. (13900 - 7500) = Rs. 6400.

Let x be the amount of B and 13900-x be the amount of A then without subtract we can find the value o B.

@ Aditi.
Nice explanation.
they asked for scheme B so we shld take x=13900-y instead of y=13900-x.

I can't understand. If we use the formula ptr/100, how to identify 'r' in that? Please explain me.

Why it has not taken X for B's principal? Then it is easy to solve without subtract again.......

Can't we solve it using alligation and mixture?
Because I tried and could not get the answer.

Can anyone solve by taking x as a value of B? Am getting different answer if I take x for B.
