Hi everyone. I'm currently working on the following problem

So i am having trouble understanding what it means by worst-case equivalent resistance. I understand the following: The worst case path for the PUN is when only on path exists between the Output and Vdd. This occurs when EFGHIJ = 011011. For the PDN the worst case occurs again when only one path (longest) exists between the output and GND. Int his case it occurs when EFGHI = 111001. Okay so i understand this much. I also know that transistors in series are added and in parallel are halfed. so EF for PDN would be 2R and HI for PUN would be R/2 as an example. but how do i calculate the worst case resistance? How do i calculate the Width? I'm looking more to understand what it is asking me to find, than the final answer. how do i approach this problem?
