A supplier supplies cartridges to a news paper publishing house. He earns a profit of 20% by selling cartridges for Rs. 540. Find the cost price of the Cartridges ?

1) Rs. 500
2) Rs. 480
3) Rs. 450
4) Rs. 400

• c) Rs. 450
  Cost price= 540*(100/120)=450
• 10 years agoHelpfull: Yes(22) No(2)
• c)450
  540/1.2=450
• 10 years agoHelpfull: Yes(6) No(1)
• let Cost Price(C.P) = x
  gain%={(S.P-C.P)/C.P}*100
  20={(540-x)/x}*100
  20/100=(540-x)/x
  x=5(540-x)
  6x=2700
  x=450
  So,Cost Price= Rs.450

• C.P=(100/100+gain%)*S.P
  C.P=100/120*540
  C.P= 450

• Profit%=profit*100/cp
  20=(sp-cp)*100/cp
  cp=450
• 10 years agoHelpfull: Yes(1) No(0)
• cp profit sp
  100 20 120
  x 540
  do cross multiplication
  540 * 100 =120 * X
  X = 540*100 / 120 =450

• sp=120/100*cp
  cp=(540*100)/120=450

• 20% of 450 =90
  therefore 450+90=550

• 120********>540
  100********>?
  (540*100)/120=450
  ans 450
• 9 years agoHelpfull: Yes(0) No(0)
• profit=20%
  s.P=540
  s.p=120/100*x
  540=6/5*x
  x=540*5/6
  x=450
• 9 years agoHelpfull: Yes(0) No(0)
• OPTION C: RS.450
• 9 years agoHelpfull: Yes(0) No(0)
• 
  profit= 100+20= so 120
  CP=(100/120)*540 = 450
• 9 years agoHelpfull: Yes(0) No(0)
• 450
  in 450 20% is 90
  so 450+90=540
  i will go through based on answer

• 120% of cp is 540 so 120% is 540 100% is 450.

• 100%=x
  120%=540
  X=(540*100)/120
  X=450

• Ans:3) Rs.450
  cp=100/(100+gain%)*sp
  cp=(100/(100+20))*540
  cp=450
• 7 years agoHelpfull: Yes(0) No(0)
• 120%--->540
  100%--->x
  X=(100*540)%120
  X=400

• answer=Rs.450(C)
  sp=(100+p/100) *cp
  540=(100+20/100)*cp
  cp=450

• given -
  
  selling price = 540
  profit = 20%
  
  formula for finding cost price = ((100/ 100+ profit))*sp
  
  (100/100+20)*540 = 450
