Question

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.

Answer 1

Given that x denotes the no of toys product in a day
The cost of production of each by =55- no. of toys produced in a  day

=(55-x)

Total cost of production is nothing but product of no. of toys produced in a day and cost of production of each toy

The required quadratic from of the given data is x²-55x+750=0
