In 4 hrs 21 parts
So,
In 1 hour 4x=21
x=21/4 = 5.25
So, no. of parts made in 7 hours is equal to the no. of parts made in one our multiplied by 7.....!
That is,
= 5.25x 7
= 36.75 parts

Mathematically the answer is 36.75, but really it depends on the location of the worker. Employees in the EU are allowed to take breaks of 20 mins every four hours worked. So it will be slightly less.
If you are talking about a worker in a sweatshop in China, Vietnam, Cambodia, Mexico or Korea, it will be the full figure of 36.75 or realistically 36.
However, going by the name of the employee, "Frank" cannot be an Asian or a Latin American, and hence should be of USA or EU origin. So the figure is less than 36.

21 divided by 4 (5.25) times 7 equals 36.75
So he will have made 36 parts and be three quarters done on the 37th part.

21/4=5.25 parts/hr
in 7 hrs
5.25*7=36.75
Since there can't be a fractional part, the answer is 36
