An electric cable costs ₹200 . If the cable was 3 meters longer and each metre of cable costs ₹2 less , the cost of cable would have remained unchanged.

Represent the above situation in the form of a quadratic equation.


Let the length of the cable be x metres.. so cost of each cable=200/x....so a/q=200/x-200/x+3=2=>3/x^2-3x=1/100=>0=x^2-3x-300(ans)
