In a shop, shirts are usually sold at 40% above the cost price. During a sale, the shopkeeper offers a discount of 10% off the usual selling price. If he manages to sell 72 shirts for Rs 13.608, then his cost price per shirt, in Rs, is

• suppose cost price is x
  so selling price is 14x/10
  now after 10% discount selling price is 126x/100
  total selling price is 72*126x/100
  72*126x/100=13608
  x=150
  so the cost price per shirt is 150.

• according to given condition (c.p(140/100))(90/100)=189
  where one shirt cost he finally selled 13608/72=189
  so c.p=150

• suppose cost price=100
  then marked price is 40% above the cost price.so marked price=100*140/100=140
  then he had given a discount of 10% so selling price=140*90/100=126.
  selling price of one shirt=13608/72=189.
  but our calculated selling price when cost price is 100=126
  so 126*x=189
  x=189/126=3/2.
  therefore cost price=100*3/2=50*3=150.
