To solve this problem, we can use the formula for simple interest:

Simple Interest = (Principal * Rate * Time) / 100

Let's assume that Mr. Kalia invested Rs. x in scheme A. Therefore, he invested Rs. (16500 - x) in scheme B.

Now, we can calculate the interest earned from scheme A and scheme B separately.

Interest from scheme A = (x * 10 * 2) / 100 = 0.2x
Interest from scheme B = ((16500 - x) * 12 * 2) / 100 = 0.24(16500 - x)

According to the given information, the total interest earned was Rs. 3620. Therefore, we can set up the following equation:

0.2x + 0.24(16500 - x) = 3620

Simplifying the equation:

0.2x + 3960 - 0.24x = 3620
-0.04x = -340
x = -340 / -0.04
x = 8500

Hence, Mr. Kalia invested Rs. 8500 in scheme A.

Therefore, the correct option is d) None of these.
