Question

A cottage industry produces a certain number of potteries in a day. It was found that the cost of production of each article ₹5 more than twice the number of potteries produced in a day. If the cost of production on that day was ₹168, find the number of potteries produced​

Answer 1

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
