He invested $ 8500 at the interest of 5% and $ 6500 at the interest of 3%

Step-by-step explanation:

Let the sum invested at interest rate of 5% be X

Let the sum invested at interest rate of 3% be Y

As we know

X + Y = 15000 - Eq (1)

X* 5/100 *1 + Y * 3/100 * 1 = 620

5X + 3Y = 62000 ---Eq (2)

Multiplying Eq (1) by 3 we get -

3X + 3Y = 45000

Substract Eq (1) from Eq (2) we get

$5X + 3Y = 62000\\- 3X -3Y = -45000\\2X = 17000\\X = 8500\\Y = 15000-8500 = 6500$

He invested $ 8500 at the interest of 5% and $ 6500 at the interest of 3%
