1. Mr.khan invested an amount of TK. 13,900 divided into two different schemes A and B at a simple interest rate of 14% per annum and 11% per annum respectively. If the total amount of simple interest earned in 2 years be Tk. 3,508, what was the amount invested in Scheme B?
- A. TK. 6400
- B. TK. 6400
- C. TK. 6400
- D. TK. 6400
Answer: Option D
Explanation:
3508=x×2×14100+(13,900−x)×2×11100
350800=28x+22(13,900−x)
Simplifying, we have:
350800=28x+305800−22x
6x=350800−305800
6x=45000
Solving for x, we have:
x=450006
x=7500
Hence, the amount invested in scheme A is. 7500.
