Answer:
The answer is "rate 12%, 14%, 16% and value 4000, 10000, and 7000".
Step-by-step explanation:
Let the value is x, y, and z. so,
The value of x amount will be borrowed at 12%
The value of y amount will be borrowed at 14%
The value of z amount will be borrowed at 16%
If the total amount= 21000
If the total interest= 3000
calculating the total interest:
The overall amount borrowing at 12% and 14% was half as much as the amount borrowed at 16%.
by calculating the value we have 3 equations that are:
calculate the matrix by above-given value:
by solving the above matrix we get:
