Answer:
A.Inversely proportional as greater is the cost of any commodity , lesser will the consumer be willing to buy
B.Directly proportional. assuming speed to be constant, if distance between two places is greater, then time taken to reach there will also be long
C.The more distance you travel for instance, in a auto rickshaw , the more will be the fare charged for it.So directly proportional
D.Inversely proportional because if number of persons eating one container of food is increased from 2 to 4 the food will get finished faster and thus will last for less number of days.
