Question

an article is bought at 45 per dozzen and sells at 85 per score find gain or loss percent

Answer 1

The purchase price of article is Rs 45 per dozen, which means 12pcs

Therefore purchase price per pc is 45/12=Rs 3.75

Selling price is Rs85 per score...one score means 20

Therefore the selling price per pc is 85/20= Rs 4.25

PROFIT = Selling price - purchase price ...which in this case is

Rs4.25 - Rs3.75= .50paisa

Therefore gain percentage will be   .5/3.75*100 =13.33%.
