3. 👉  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?

1. A. Rs. 6400

2. B. Rs. 6500

3. C. Rs. 7200

4. D. Rs. 7500

1. 👉 Answer & Explanation:

   Suppose the Thomas invested sum in Scheme A is Rs. X and that in Scheme B is 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, invested sum in Scheme B = Rs. (13900 - 7500) = Rs. 6400.
