B Correct answer
Explanation

Let the cost price be x. Initial selling price is 1.05x. If cost price is 0.95x and selling price is 1.05x - 1, the profit is 10%, so 1.05x - 1 = 1.10 * 0.95x. Solving this gives 1.05x - 1 = 1.045x, which leads to 0.005x = 1, so x = 200.

A Correct answer
Explanation

Profit = SP of 5 pairs. Since Profit = SP - CP, we have SP(5) = SP(21) - CP(21). Thus, CP(21) = SP(16). This means SP/CP = 21/16. Profit percentage = ((SP-CP)/CP) * 100 = ((21-16)/16) * 100 = (5/16) * 100 = 31.25 percent.
