Apolice office will hold an 18-session lesson. for every session, there are 7 days and there is no break between every two sessions . if the session can only be hold on weekdays and if the first session start on friday, what day is the last day?

Wednesday

Step-by-step explanation:

A 18 sessions and we know that a session lasts 7 days. We also know that the sessions are grouped and that there is only a break after every 2 sessions. The sessions can only be held on weekdays which is 5 days. The first session starts on Friday. We need to determine the last day of the 18 sessions.

WE can assume that a break is a one day.

The first two sessions will be a total of 14 days and then a break. Friday adding 14 days will result in the first two sessions ending on Wednesday and a break day. The next two sessions will start Friday again.

Therefore the sessions are even number of 18 and therefore will always end on a Wednesday
