First of all, we need to find out the relation between 1 USD to franc. As we know 0.0625 USD = 1 franc.

So, 1 USD = 16 Franc

So, the total Francs spent are:

300×16

To get the grams of pearl bought we need to divide the total francs spent by francs spent per gram.

=> 300 × 16/320
=> 15

So, the answer is 15 grams which is option D.
