It cost a college Rs.0.70 a copy to produce a Programmed for the homecoming football game. If Rs.15,000/- was received for advertisements in the programme, how many copies at Rs.0.50 a copy must be sold to make a profit of Rs.8000/- ?

• Let the no. of copies be x.
  We know Profit = Selling Price - Cost Price.
  Here s.p = Rs. 0.5*x
  c.p = Rs. 0.7*x-15000
  profit = Rs. 8000
  
  Therefore, 8000 = 0.5x - (0.7x - 15000)
  x = 35000

• 35000!!!
  8000=0.5x-(0.7x-15000)

• ans:35000
  total profit is 8000,(15000-8000=7000)
  loss=0.5-0.7=-0.2
  7000/0.2 =35000 print copys

• we have to get 7000 loss.........for every 5copies,1rupee loss..so 35000copies have to be sold

• 14000
  for advertisements 15000
  total profit must be 8000
  therefore 15000-8000=7000
  they have to sold x no. of copies for Rs 7000
  one copy=.50
  x*copy=7000
  x=7000/copy
  x=7000/.5
  x=14000 no of copies

• Copy is sold at loss =0.70-0.50=0.20
  Even then a profit of 8000 is made.
  Let N be no. of copies.
  Therefore,
  (N*0.2)+8000=15000
  N*0.20=7000
  N=35000
  So 35000 copies sold

• 0.70*X+8000=0.50*x+15000
  =35000

• for 0.70 there cost rs.15000
  if it is sold for 0.50 then what is the selling price to gain the profit of 8000??
  so 0.50x-0.70*15000=8000
  x=18500
