b) +2.5%
c)-9.75%
d)+10.5%

• this can be esily solved by assuming
  
  assume 100 seats n 100/- per seat
  total revenue if all seats full-10000
  
  now reduced by 5%
  seats-95 price per seat-95
  95x95=9025
  
  therefore
  loss=(975/10000)100 = 9.75%
  
  ans- C -9.75%

• say seats = 100
  price = 100
  revenue = 10000
  
  new seats = 95
  new price = 95
  new revenue = 9075
  
  change in revenue = 9025-10000 = -975
  % change = -9.75
  
  Ans
  C) -9.75%

• let price of each ticket be rs.10and there b 100 tickets
  5%decrease means decrease of rs.50 on tthe tickets and decrease of 5 tickets which cost rs.50
  total loss=rs.100/1000*100=-10%

• Let S be the actual Seat , P be the Price . So Revenue R= S*P
  After Reduction actual Seat= 0.95S and actual Price=0.95P
  i.e Revenue now = 0.95S*0.95P
  =0.9025 S*P
  So Effect on Revenue is 1-0.9025= 0.0975
  
  Hence Answer is C) -9.75%
