CorrectNot quiteAnswer B

Correct answer: B

Explanation

  1. The customer takes 4 bars but pays for 3.

  2. 1 bar out of 4 is free.

  3. Discount % = 14×100=25%\frac{1}{4} \times 100 = 25\%.

Worth noting

The free bar must be compared with ALL the bars received (4), not with the bars paid for (3). 13\frac{1}{3} gives the tempting 3313%33\frac{1}{3}\%.
