If the price of petrol is increased by 30%,by how much % the car owner must reduce his consumption in order to maintain the same budget?

• let earlier amount=100Rs,increase in amount=130rs
  amount of money consumed earlier=amount of money consumed later
  let X be the earlier amount of petrol being filled and Y be the later amount of petrol
  therefore 100*X=130*Y
  Y%X=76.923
  therefore % decrease=23.077%(answer)
