A cottage industry produces a certain number of toys in a day. The cost of production of each toy (in rupees) was found to be $55$ minus the number of articles produced in a day. On a particular day, the total cost of production was Rs. $750$. If x denotes the number of toys produced that day, form the quadratic equation to find $x$.
Given:
A cottage industry produces a certain number of toys in a day.
The cost of production of each toy (in rupees) was found to be $55$ minus the number of articles produced in a day.
On a particular day, the total cost of production was Rs. $750$. $x$ denotes the number of toys produced that day.
To do:
Here, we have to form the quadratic equation to find $x$.
Solution:
The cost of production of each toy $= 55 - x$
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 $ =x (55 - x)$
Therefore,
$x(55-x) = 750$
$55x-x^2 = 750$
$x^2-55x+750 = 0$
The required quadratic equation is $x^2 – 55x + 750 = 0$.
