Question

Ashin invested an amount of Rs. 13,900 divided into 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 (in rupees)?

___

Answer 1

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

Then

$\frac{14\times x\times 2}{100}$+$\frac{(13900-x)\times 11\times 2}{100}$=3508

28x - 22x = 350800 - (13900 × 22)

6x = 45000

x = 7500

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