Q23

by JinZ551 Mon Dec 20, 2021 2:52 am

can anyone demonstrate how to quickly solve this question?


from the question stem I divide it into two frames: t can either be 1 or 2

if t is second week, then"
_ _ _ k l
_ t v _ _

because w cannot be 4th, so w have to be 5
an because o and z has to be together, they must be in first week

o (j/n) (j/n) k l
z t v y w

things become complex when t can be in first week, but this first frame (with t in second week ) is enough to solve the question.

i am wondering if anyone has better thought process to solve this quesiton.
