Question

Identify the type of variation for the following

(1) Area of land and its cost
(2) Number of workers and the time taken to complete the work

Answer 1

Step-by-step explanation:

2)) We know that more is the number of workers to do a job, less is the time taken to finish the job.

So, it is a case of inverse proportion.

1))Clearly, more is the area of cultivated land, more is the crop harvested.  

So, it is a case of direct proportion. 

HOPE IT HELPS YOU....
