A printer manufacturer initially makes a profit of 12 % by selling a particular model of printer for Rs 6500. If the cost of manufacturing of that printer increases by 25 %, then price paid by customer is increased by 15 %. Find the % profit made by the manufacturer ?
a) 5%
b) 6%
c) 4.5%
d) 9 %
e) None of these

• new sp=old sp+15% of old sp
  new sp=6500+(6500*15/100)
  =6500+975=rs7475
  old cp=88% 0f old sp
  6500*88/100=5720
  new cp=25% of old cp
  = 5720*25/100
  =7150
  profit %= (gain*100)/cp
  profit %= ((7475-7150)*100)/7150
  =(325*100)/7150
  =50/11
  =4.5

• Here price paid by customer is increased by 15 % means selling price increased by 15 %
  
  So, new selling price of printer is = 6500 + 15 % of 6500 = 6500 + 975 = 7475
  
  New cost price of printer = Old Cost Price + 25 % of Old Cost Price -----------(a)
  
  Old Cost Price = 6500 - 12 % of 6500 = 6500 - 780 = 5720
  
  Now put the value of Old Cost Price in Equation (a)
  
  New cost price of printer = 5720 + 25 % of 5720 = 5720 + 1430 = 7150

• sp=6500------------------> profit = 12%
  
  orginal price is 6500-12%of 6500
  
  6500-6500*12/100=5750
  new sp =6500+6500*15/100=7475
  new cp=25%of 5750
  
  p%=new sp-newcp/newcp *100
