A restaurant has priced pork at 95 rs. Now it reduces its price by 20% so that it earns 60% more. Now what is the percentage increase in the consumption of pork. Question was exactly like this.

option)100% b)10%

• Let the initial price and consumption be 100 and 100.
  The total revenue is 10000
  The final price is 80 and final revenue is 16000
  So, final consumption is 16000/80 = 200
  Percentage increase = 100, choice (1)

• In this problem, the percentage changes are more important compared to the actual values. For, that reason, we can ignore the actual values.
  For that reason,for the simplicity in the calculations, lets assume the price of pork to be 100 and the amount of sales to be 100.
  
  So, teh total revenue is 100 * 100 = 10000
  
  Now, as the revenue has gone up by 60%, so the new revenue is 16000.
  As the cost of the pork is decreased by 20%, the new price of the pork is 80
  
  So, the new total sales = 16000/80 = 200
  We can observe the value of sales has increased from 100 in the previous case to the new value 200.
  It increased by a value of 100 , which is equal to 100, which in turn is equal to 100%
  100% is the answer
  
  Alternatively,
  
  Even if we take the cost as 95, the new price is 20% less than 95, so the new price is 76.
  Let the initial sales be 100, so total revenue is 9500
  The revenue has gone up 60%, so new total revenue 9500 * 1.6
  
  The new sales = revenue/ new price = 9500 * 1.6 / 76 = 200
  The increase in the sales = 100
  Percentage increase = 100%

• 20 % of 95 = 19 ;
  new price after reduction = 95-19 = 76 ;
  in order to earn 60& more: 76 x 100 / 160 = 95/2;
  increase in consumption : two times the previous price
  => 100%

• 100 pork consumption at 95
  then revenue = 95 * 100 =>9500
  
  Now reduce price of pork is 76
  so to earn more 60 % profit
  
  x is the increase in consumption.
  
  original + increase = reduce price with increase consumption.
  9500 + 60*9500/100 = 76 * (100 + x)
  solve get x = 100
  so % increase in consumption is 100%

• ans is 100%
  solution:- let no of porks sold initially=x
  so total earning initially=95x
  As now price is reduced by 20%, so new price = 95*80/100 =76
  since earning has been increased by 60%, so now his earning will be 95x*160/100 =152x
  therefore no of porks sold=152x/76 =2x
  so increase in selling=2x-x =x.
  hence %age increase=100%

• 100-80-160 so increase in 100%.
• 11 years agoHelpfull: Yes(0) No(2)
• when the price is reduced by 20%,
  increase in consumption=r% * 100/(100-r)%
  =20 * 100/80=25%
• 10 years agoHelpfull: Yes(0) No(0)
• 100%
  as decreased price is 76rs
  let it sell 100 at rs95
  to earn 60% more 9500*160/100
  so at 76 rs he has to sell
  9500*160/(100*76)=200
  hence % increase=100%

• @95 earning=95x, now by reducing price 20% it earn 60% =95x.60%= 152x
  after reducing price by 20% per pork =76.let total conumption y.
  total earning = 76y=152x
  y:x=2:1
  in percent 100% consumption increased.

• Let price =P, consumption=C, Earning=E.
  so P * C = E------------(a).
  new price=P1, consumtion=E1, Earning=E1.
  so P1 * C1 = E1.----------(b).
  
  now (a)/(b)= (P/P1) * (C/C1) = (E/E1)-------(c).
  
  P1=P +20%P =>P/P1=100/80.
  
  similarly E/E1=100/160.
  
  putting these values in (c).
  
  C/C1=1/2.
  
  => C1/C=2
  
  =>(C1/C)-1=2-1.
  
  =>(C1-C/C)=1.
  
  =>(C1-C/C)*100 = 100%. (ans)
