Answer:
The number of articles produced on that day = 6 articles
The cost of production of each article = Rs 15
Step-by-step explanation:
Given that:
A cottage industry produces a certain number of pottery articles in a day.
It was observed on a particular day that the cost of production of each article (in rupees) was 3 more than twice the number of articles produced on that day.
The total cost of production on that day was 90.
To Find:
The number of articles produced and the cost of each article.
Let us assume:
The number of articles produced on that day be x.
The cost of production of each article = 2x + 3
We know that:
Each article costs = Rs (2x + 3)
x articles cost = Rs (2x + 3)x
Finding the value of x:
According to the question.
x articles cost = Total cost of production
⟶ (2x + 3)x = 90
⟶ 2x² + 3x = 90
⟶ 2x² + 3x - 90
⟶ 2x² + 15x - 12x - 90 = 0
⟶ x(2x + 15) - 6(2x + 15) = 0
⟶ (x - 6) (2x + 15) = 0
⟶ x = 6 or x = - 15/2
We have to take the value of x equals to 6. Because we have assumed that x is the number of articles which should be a positive number.
Now,
The number of articles produced on that day.
Number of articles produced = 6 articles
The cost of production of each article.
Cost of each article = 2x + 3
Cost of each article = (2 × 6) + 3
Cost of each article = 12 + 3
Cost of each article = Rs 15
