Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Gain:1009100\over9%.

Let CP of 1 article = ₹1
CP of 50 articles = ₹50
Given: SP of 45 articles = ₹50
SP of 1 article = ₹50/45 = ₹10/9

Gain per article = ₹(10/9 - 1) = ₹1/9

Gain% = (1/9) × 100 = 1009100\over9%
