after 3 years for 30,000 principal is 9000.
What would be the interest on 7500 at the same
rate of interest for the same period?
​

Answer 1

Answer:- 2,250

Step-by-step explanation:

Here the simple interest given is 9,000. So, first do this:-

30,000 x 3 x X / 100 = 9000

9,000 x 100 / 30,000 x 3 => 900,000/90,000 = 10 Percent = Rate of Interest

Now, 7,500 x 10 x 3 / 100 = Answer

Cancel out 2 Zeroes at 7,500 and 100.

Multiply 3 with 75, you'll get 225.

Multiply 10 with it, you'll get 2,250.
