Answer 2

Answer:

By unitary method

Cost of 12 bags=174

so cost of 1 bag = 174 ÷ 12 = 14.5

Cost of 20 bags= 20× cost of one bag

20×14.5=290

Thus cost of 20 bags is 290

By proportion method

12:174::20:x

product of means=product of extremes

174×20=3480

12x=3480

x=3480÷12

x=290

So the answer is 290
