Question

there are some toys  if  the cost of production of each toy (Rs.)was fou to be 55 minus the no.
of articals produced in a day.on a day, total cost of production  was 750 rs. formulate quadratic equation

Answer 1

Let the number of toys produced in a day = x
Cost of each toy = Rs(55-x)
Total cost = No.of toys × cost of each toy
                 = x × (55-x)
                 = 55x - x²

given that 55x - x² = 750
⇒x²-55x+750=0   (required quadratic equation)
