Manoj was a very careless driver, so his owner Ganpat gave him an offer that he will get an incentive of Rs30 for every bottle-box he delivered without breaking it and he will be charged Rs 90 for every bottle-box he broke.Ganpat gave Manoj 100 bottles-box to deliver. After delivery Ganpat paid Manoj Rs 2400.
How many bottles-box did Manoj break?
Manoj delivered 95/100 bottle-box safely.
Let us say S: safe no of glass box delivered, B: no of glass-box broken
30G - 90B = 2400
G + B = 100
Solving the simultaneous equations will give G=95, B=5
