From who's book/material is this?

Can someone please help answer the following questions?

C3.Using the fixed fastener formula calculate the true position tolerance for the two patterns shown below. (Show your work).

C3.1. The size of the bolts are (diameter) 0.492 – 0.500 and the size of the clearance holes are (diameter) 0.520 – 0.536.

C3.2 The size of the bolts are (diameter) 0.245 – 0.250 and the size of the clearance holes are (diameter) 0.2656 – 0.270.

C3.3 Use the floating fastener formula and calculate the true position tolerance for the above 4 hole pattern, given the size of the bolts are (diameter) 0.492 – 0.500 and the size of the clearance holes are (diameter) 0.520 – 0.536.

C3.4 Using the floating fastener formula calculate the plus/minus tolerance for the holes shown above if the bolts are 0.370 – 0.375 and the clearance holes are 0.386 – 0.397.

C3.5 Repeat the above calculation using the fixed fastener formula.
