An article was sold at a 10% loss. Had it been sold for Rs. 108 more, there would have been an 8% profit. Find the cost price. MCQ with Answer and Explanation

Explanation:
Let CP of 1 = 1, CP of 8 = 8, SP of 6 = 8 => SP of 1 = 8/6 = 4/3 = 1.333, gain = 33.33%.

Explanation:
Cost Price of 1 pencil = 10 / 12 = 5 / 6. Selling Price of 1 pencil = 12 / 10 = 6 / 5. Profit = (6 / 5) - (5 / 6) = (36 - 25) / 30 = 11 / 30. Profit percentage = ((11 / 30) / (5 / 6)) * 100 = (11 / 25) * 100 = 44%.
