• 60%
  let there be 100 visitors = 25p *100 = 2500 is orignal revenue.
  now new price = .80 * 25 = 20p.
  new revenue = 1.28 * 2500 = 3200
  new visitors = 3200/20 = 160
  increase = 60 %

• sir, plz explain.. i hav a doubt. if the sale of ticket was increased by 28% then obviously the increase in percentage of visitors is also 28%.

• if sale of ticket increases by 28% then number of visitors will increase 28%. But if the amount collect by zoo authority will increase 28% then number of visitors will increase by some percentage.
