Give example of Graphs of two variables measured in different units.....
Nd explain it

Dear student,

An example of graphs of two variables measured in different units is - quantity of coffee traded from year 2010 - 2015 and their price in Rupees. 

Here there are two variables, quantity and price. Quantity is expressed in Kilogram and price is expressed in rupees. 
In graph of two variables two different scales are taken for variable, one on left side and one is on right side. 
In given example year will be taken on X-axis, and other variables i.e. quantity and price will be taken on left and right side respectively.

Regards
