Show answer & explanation

Correct answer: B

Concept

Profit or loss is measured against cost price. For one article, let the cost price be C and the selling price be S.

If S/C is below 1, the difference is a loss; the loss percentage is ((C − S)/C) × 100.

Application

  1. The given total-price relation is 30S = 25C.

  2. Dividing both sides by 30C gives S/C = 25/30 = 5/6.

  3. Thus the loss fraction is (C − S)/C = 1 − 5/6 = 1/6.

  4. Converting the fraction to a percentage gives (1/6) × 100 = 16⅔%.

Cross-check

Taking C = ₹6 gives S = ₹5. Then 30 articles sell for ₹150 and 25 articles cost ₹150, so the given relation is satisfied.

Result

Therefore, the transaction results in a loss of 16⅔%.
