Question

20 articles box is purchased for 5400 rupees after 20% discount find the cost price of each article

Answer 1

Let

cost of 20 boxes be Y

20 boxes cost after 20% discount = 5400

=> Y -20% of Y = 5400

=> Y - 20/100 × Y = 5400

=> Y - 1/5 × Y =5400

=> 4/5 Y = 5400

=> Y = 5400 ×5/4

=> Y = 6750

Cost of 20 boxes =Rs 6750

Cost of 1 box = 6750 ÷ 20

=Rs 337.5
