let C be rate of 1 chef, x be total chef on weekend

3C = 225/5 =45
C= 15

Required eqn:
x * C * 10 = 750
x= 5 = 3+ 2

answer = 2 additional chefs (D)

Total burgers by 3 chefs:
3 chefs........225 burgers.....5 hours

Total burgers by 3 chefs per hours [225/5 = 45]
3 chefs........45 burgers.......1 hour

Total burgers by 1 chef per hour [45/3 = 15]
1 chef.......15 burgers..........1 hour

Now, 750 burgers were made in 10 hours on the weekend, which means 75/10 = 75 burgers were made per hour.

Let x be the total number of chefs working on the weekend.

Thus, 15x = 75
x = 5

3 were already working with the restaurant. So the restaurant employed 2 more on the weekend.

Answer is D.

Let x be the no. of chefs working on the weekends
=> 225/(3)(5) = 750/(10)(x)
=>x = 5

No. of additional chefs = 5 - 3=2

Hence D
