Step-by-step explanation:
Let there be x articles.
Then the production cost of each article =3+2x
Total production cost =x(3+2x)=90
3x+2x
2
=90
2x
2
+3x−90=0
2x
2
+15x−12x−90=0
2x(x−6)+15(x−6)=0
(2x+15)(x−6)=0
x=6,−
2
15
Number cannot be negative.
So, number of articles =6 and the cost of each article =Rs.15
