Answer:
amount paid at a rate of 9% = 90000
amount paid at a rate of 7% = 170000-90000=80000
Explanation:
We have given total amount = $170000
Let amount paid at rate of 9% is x
Then amount paid at a rate of 7% = 170000-x
We know that sum of individual interest will be equal to total interest
So
So amount paid at a rate of 9% = 90000
And amount paid at a rate of 7% = 170000-90000=80000
