if the price of petrol increased by 25% and john intends to spend only an additional 20% on petrol by how much % will he reduces the quantity of petrol purchased?

• the increased price is 25 % and john intend to spend 20 % only.. so the difference is 5%
  so (5/125) * 100= 4%

• If earlier consumption is 1 ltr for Rs 100, then
  
  New price of 1 ltr petrol = Rs 125
  
  Oil purchase from Rs 120 = 120/125 = 24/25 ltrs
  % Reduction in qnty purchased = 100*(1/25)/1= 4%

• take initial amount as 100 it increase 25% it will be 125 but he spent 20% so 120
  ((125-120)/125)*100=4%

• incresed part of petrol is .25 of petrol
  .25x=.2
  x=4/5
  so reduction is 4/5*100=80%
  100-80=20%
