2. Answer:

   first convert mixed fraction into improper fraction

   3 1/2 = 7/2

   270 3/8 = 2163/8

   find the cost of 1 litre petrol is

   = 2163/8 ÷ 7/2

   = 2163/8 × 2/7

   = (2163÷7) / (8÷2)

   = 309/ 4 rupees

   then, cost of 4 litre petrol is

   = 309/4 × 4

   = 309/(4÷4)

   = 309/1

   = 309 rupees
