Answer:
→ Let the number of toys produced on that day be x
→ Given that The cost of production of each toy (in rupees) was found to be 55 minus the number of toys produced in a day.. The cost of production of each toy that day= Rs. (55-x)
→ So that total cost of production that day= Rs. x(55-x)
→ Given that On a particular day, the total cost of production was Rs.750.
..x(55-x) = 750
⇒ 55x-x² = = 750
⇒ x² - 55x + 750 = 0
.. We can see, equation given in question is correct.
