80%

Step-by-step explanation:

To calculate the use of the bottleneck resource, the following formula is used:

Flow / Capacity

Now the flow rate is calculated by means of the cycle time, the flow rate is equal to the inverse of the cycle time (50 minutes), as shown below:

Flow rate = 1/50 = 0.02 client per minute.

Bottleneck capacity is the multiplication of the inverse of each activity, that is:

(1/1) * (1/40) * (1/10) = 0.025 client per minute.

Now replacing in the initial equation:

Flow / Capacity = 0.02 / 0.025 = 80%.
