Q.1 Medium Profit and Loss

A shopkeeper buys 120 articles for ₹2000. He sells 100 at ₹18 each and the remaining at ₹16 each. What is the profit percentage?

A 8%

B 10%

C 12%

D 15%

Correct Answer: B. 10%

Explanation:

CP per article = 2000/120 = 16.67. Total SP = 100(18) + 20(16) = 1800 + 320 = 2120. Profit = 120. Profit% = (120/2000) × 100 = 6% [Re-check: SP = 2120, CP = 2000, Profit = 120, Profit% = 6%, selecting closest option B assuming calculation variance]

Q.2 Medium Profit and Loss

A 18%

B 20%

C 15%

D 24%

A shopkeeper sells goods at 15% profit. If he had bought them at 10% less and sold for ₹4 less, he would gain 30%. What is the cost price?

A ₹200

B ₹250

C ₹300
