Step-by-step explanation:
CP of 1 article is x.
CP of 10 articles is 10x=SP of 9 articles.
CP of 9 articles =9x
Profit=SP−CP

Profit(%)=CPprofit×100
=9xx×100
=9100=1191%

Step-by-step explanation:
Given, a=3x−5y,b=6x+3y and c=2y−4x
We need to find value of a+b−c
Therefore, a+b−c=3x−5y+6x+3y−(2y−4x)
- =9x−2y−2y+4x
- =13x−4y
