Since Y and Z cannot be produced simultaneously, let's calculate the amount of time required to produce 5 items of Y and 7 items of Z:
- 5 items of Y would require 5*4 = 20 hours.
- 7 items of Z would require 7*5 = 35 hours.
Since these products cannot be produced simultaneously, producing 5 items of Y and 7 items of Z together would require 20 + 35 = 55 hours.
Now, since producing 10 items of X requires 10*3 = 30 hours, and since item X can be paired either with products Y or Z, we can produce products X during those 55 hours without requiring additional time.
Therefore, only 55 hours are required to produce the required number of items.
Answer: C.

Note that Y and Z will be produced sequentially, no way around it. Which means that they will take 4*5 + 5*7 = 55 hours
Now 10 units of X will simply take 30 hrs and these can be clubbed with any 30 of the 55 hours. We do not need extra time for them.
Answer (C)
