Step-by-step explanation:

(i) if numbers of article is increasing then cost will also increase. So it is a case of direst proportion

(ii) Cost will also increase when weight of the article is increasing. So it is a case of direst proportion

(iii) Time will increase when distance will increase, if speed remaining constant. So it is a case of proportion

(iv) Wages will increase if the number of working hours is increasing. So it is a case of direst proportion

(v) For same distance time taken will reduce if speed is increased. So it is not a case of direst proportion

(vi) Cost for the land will increase if its area will increase. So it is a case of direst proportion

Answer:

Answer :-

(i) Number of articles (x) and their price (y)

If number of articles is increasing then cost will also increase. So it is a case of direct proportion

(ii) Weight of articles (x) and their cost (y).

When weight of the article is increasing then cost also increase. So it is a case of direct proportion

(iii) Distance x and time y, speed remaining the same.

Time increases when distance increases, if speed remains constant. So it is a case of direct proportion

(iv) Wages (y) and number of hours (x) of work.

Wages increases if the number of working hours increases. So it is a case of direct proportion

(v) Speed (x) and time (y) distance covered remaining the same).

For same distance time taken will reduce if speed is increased. So it is not a case of direct proportion

(vi) Area of a land (x) and its cost (y).

Cost of the land increases if its area increases. So it is a case of direct proportion
