Solution

Let the number of pottery articles, produced on a particular day be x.

Cost of production of each article = Rs.(2x + 3)

⇒

⇒

⇒

⇒

⇒ x = 6 or (rejected as the cost cannot be negative)

∴

Hence number of articles produced in a day = 6

Cost of production of each article = Rs. (2 × 6 + 3)
