3 chefs are able to make 225 burger per 5 hours and that means 45 per hour and each chef is making 15 burgers/h
And during the weekend the restaurant employs more chefs so that they are able to make 750 burgers/ 10 hours = 75 burgers/hour.
Therefore, the number of chefs during weekend is= 75/15= 5.
And the question asks about the difference between weekday and weekend which is 5-3=2.
