Show answer & explanation

Correct answer: B

Concept

In a pie chart, each shop's share of a total equals its percentage multiplied by that total. Two separate totals apply here: Chart I gives each shop's share of the combined Rings + Bracelets (total = 440), while Chart II gives each shop's share of Rings only (total = 200). For any shop, Bracelets = (Rings + Bracelets) - Rings.

Application

  1. Rings + Bracelets for Shop I = 25% of 440 = 110; for Shop III = 10% of 440 = 44.

  2. Rings for Shop I = 18% of 200 = 36; Rings for Shop III = 7% of 200 = 14.

  3. Bracelets for Shop I = 110 - 36 = 74; Bracelets for Shop III = 44 - 14 = 30.

  4. Bracelets sold by Shop I and Shop III together = 74 + 30 = 104.

  5. Rings sold by Shop IV = 40% of 200 = 80.

  6. Required difference = 104 - 80 = 24.

Cross-check

Verify the bracelets total the other way: combined items for Shops I and III are 110 + 44 = 154 and their rings are 36 + 14 = 50, so their bracelets are 154 - 50 = 104, matching step 4. Subtracting Shop IV's 80 rings leaves 24, confirming the result.
