One hundred and fifty articles of the same kind were bought by a supplier for Rs 12,570 and Rs 12.50 per article was spent on its packing, transportation, etc. If 60% of the articles were sold for Rs 115 each and the remaining for Rs 120 each; find the profit he made.
2925
Number of articles bought = 150
Cost price of these articles = 12,750
Money spent =150×12.50=1875
Total cost price = 12750 + 1875 = 14625
60% were sold
So, 60100×150=90
150 - 90 = 60
Selling price =90× Rs 115+60× Rs 120=17550
Profit = Selling Price - Cost Price
17550 - 14625 = 2925
