Question

Ashin invested an amount of Rs. 13,900 divided into two different schemes A and B at the simple interest rate of 14% per annum and 11% per annum respectively. If the total amount of simple interest earned in 2 years is Rs. 3508, what was the amount invested in Scheme B (in rupees)?

___

Answer 1

Let the sum invested in Scheme A be Rs. x.
Then, sum invested in scheme B will be Rs. (13900 - x).

Given, total simple interest earned in 2 years is Rs. 3508.
Total interest = interest from scheme A + interest from scheme B

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

$28x-22x=350800-(13900\times 22)$

6x = 45000

x = 7500

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