Question

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

Answer 1

Answer:

Let there be x articles.

Let there be x articles.Then the production cost of each article =3+2x

Let there be x articles.Then the production cost of each article =3+2xTotal production cost =x(3+2x)=90

Let there be x articles.Then the production cost of each article =3+2xTotal production cost =x(3+2x)=903x+2x² =90

=902x²+3x−90=0

+3x−90=02x²+15x−12x−90=0

+15x−12x−90=02x(x−6)+15(x−6)=0

+15x−12x−90=02x(x−6)+15(x−6)=0(2x+15)(x−6)=0

$x = 6. \: - \frac{15}{2}$

Number cannot be negative.

Number cannot be negative. So, number of articles =6 and the cost of each article =Rs.15
