Solution:
Given that x denotes the number of toys produced in a day.
So, the cost of production of each toy = (55 – x)
And the total cost of production is the product of the number of toys produced in a day and the cost of production of each toy, i.e., x (55 – x)
From the question, it’s given that
The total cost of production on that particular day is Rs.750.
So,
⇒ x (55 – x) = 750
⇒ 55x – x2 = 750
⇒ x2 – 55x + 750 = 0
Thus, the required quadratic equation is x2 – 55x + 750 = 0
