1. Answer:

   Now if the cost is increased to 12% it will be

   = 70+(12%*70)

   =84 rupees/ litre.

   So the price difference is 84–70=14 rupees/ litre.

   Now if the expenditure should be same so that Mr. Brown will pay only 70 rupees, then he must be consuming less petrol. ( i.e lesser than 1 litre.). So he will consume :

   i.e (70 rupees / 84 rupees)*1 litre= 0.8333 litre.

   Reduction in quantity of petrol consumed by Mr. Brown= 1 litre –0.83333 litre= 0.1666 litre.

   Therefore percentage reduction of petrol consumption by Mr. Brown

   =(1–0.8333)*100= 16.67 %
