If the price of the petrol raised by 20%,find by how much percent a car owner must reduce his consumption so as not to increase his expenditure on petrol?

• 50/3 %
  If earlier he used 100 Rs for 100 ltrs, now he will need 120 rs for 100 ltrs.
  but he will get 250/3 ltrs for Rs 100 now,
  So he should reduce his consumption by 100-250/3= 50/3% = 16 2/3 %
