Cost price of 30 articles is Rs. 260. Selling price of 40 articles is Rs. 260. What is the profit/loss percentage? (Cost price of all the articles is same. Selling price of all the articles is same.)
Show answer & explanation
Correct answer: B
Explanation
CP of 30 items = ₹260
CP of 1 item = 260/30
SP of 40 items = ₹260
SP of 1 item = 260/40
Loss = 260/30 - 260/40
= (1040 - 780)/120
= 260/120
Loss percentage = (260/120) ÷ (260/30) × 100
= 30/120 × 100
= 25%
