A man purchased a waten for Rs. 400 and sold it at a gain of 20% of the selling price. The selling price of the watch is:

• Ans: 500
  Guys ,You have a confusion that whether ans is 480 or 500 right?
  If the Qn is "purchased for Rs. 400 and sold it at a gain of 20% of the Cost price ?""
  Then You can say 400+20% of CP=SP ==> 400+20% of 400=SP => SP=480
  But the Qn is "purchased for Rs. 400 and sold it at a gain of 20% of the Selling price ?"
  So Formula will be: 400+20% of SP=SP => 400+0.2SP=SP => 0.8SP=400
  So SP=500

• Ans)500
  gain=sp-cp
  20%of sp=sp-cp
  cp=sp(1-20/100) -> cp=sp*4/5 ->sp=cp*5/4=>sp=400*5/4=500

• Ans: Rs 480
  cp= Rs 400 ,gain =20%, sp=(((100+gain %)/100)*cp)=480

• cp 400 gain 20%of sp
  sp= c.p + gain
  sp = cp +( 20%of sp)
  sp =400 + (sp/5)
  5sp=(2000+sp)
  4sp=2000
  sp =2000/4=500
  sp =Rs.500

• man purchased watch by 400 & they sold by gain of 20%
  therefore 400*(20/100)=80

• we use the concept of profit multiplier
  sp = cp * p.m where pm = gain% = 20 so 100+20 that = 120 and multiply it with 100 we got 1.2
  sp = 400 *1.2
  sp = 480

• sp=(100+gain)*cp/100
  sp=(100+20)*400/100

• answer can be 480 or 500, but the correct solution is 500.
  three cases arise here.
  case 1 - as it is specifically mentioned that 20% of SP. So, by using formula of gain=SP-CP,
  =>20% of SP=SP-CP
  =>20% of SP=SP-400
  =>SP-SP/5=400
  =>SP=500
  case 2 - if it is given that gain of 20%, then using formula of gain%,
  20=((SP-400)/400)*100
  ->SP=480
  case 3 - if it is given that gain of 20% of CP, then by formula of gain=SP-CP,
  20% of 400=SP-400
  ->SP=480

• ans=480
  gain%=gain*100/cp (gain%=20, cp=400, sp=(100+gain%) put this value

• 480
  he bought for 400 and gain is 80 so selling price is 480
• 9 years agoHelpfull: Yes(0) No(2)
• sp=((100+gain%)/100)*cp)=(120/100)*400=360

• COST PRICE=400
  GAIN =20%
  GAIN AMT =400*(20/100)=80
  SELLING PRICE =480

  Selling price=C.P+(C.P*gain)/100=
  
  Rs.480

• Ans=Rs. 480
  as the cost price is Rs=400
  gain%=20
  so selling price can be calculated by= 100+gain%/100 *cost price
  ie 100+20/100*400=480

• cp=400
  sp=gain of 20% of sp
  sp=cp+gain
  sp=400+sp/5
  5sp=2000+sp
  4sp=2000
  sp=2000/4=500

• SP-CP=20% of SP
  => SP-400=0.2SP
  =>0.8SP=400
  =>SP=500

• sp-p=cp
  => sp-20%of sp=cp
  sp(1-(20/100)=400 then sp =500
