Step-by-step explanation:

here

cost of 12 liters oil = RS 4800

cost of 1liter oil =rs 4800 ÷ 12 = 400

now

cost of 20 liters will be 400×20=8000

To find the answer u have to use unitary method , that is divide then multiply .so :

12l =rs4800
1L = 4800 \ 12 = 400

Therefore 20 L = 400 * 20
= 8000
Therefore 20 L OF OIL will cost rs 8000
