X sells his goods 20% cheaper than Y and 20% dearer than Z. How many % is Z's goods cheaper/dearer than Y's? Correct Answer 33.33%
Given:
X sells his goods 20% cheaper than Y and 20% dearer than Z.
Explanation:
20% cheaper
⇒ X ∶ Y → (4 ∶ 5)× 3
20% dearer
⇒ X ∶ Z → (6 ∶ 5)× 2
X ∶ Y ∶ Z → 12 ∶ 15 ∶ 10
Required percentage
= {(15 - 10)/15} × 100
⇒ 33.33%
∴ Z is 33.33% cheaper than Y.
