Let x = the selling price.

New cost = $200:
Since the profit is 20% of the selling price, the new cost = 80% of the selling price:
200 = .8x
x = 200/.8 = 2000/8 = 250.

Old cost:
Since the profit is 10% of the selling price, the old cost = 90% of the selling price:
Old cost = .9(250) = 225.

The correct answer is A.
