Logical Reasoning and Analytical Ability (CSP) Puzzle Test

Five Ships J, K, L, M and N are to be unloaded on 5 consecutive days beginning from Monday to Friday.

(i) Each ship takes exactly one day to unload.

(ii) K must be unloaded on the day, proceeding the day on which M and N are unloaded.

(iii) L cannot be unloaded on Tuesday

(iv)M is the second ship to be unloaded after J is unloaded.

If K, M and N are to be unloaded one immediately after the other, the two days on which J can be unloaded are:

Monday and Tuesday

Monday and Friday

Tuesday and Wednesday

Wednesday and Friday

Correct option 1: Monday or Tuesday

If K M N are to be unloaded one immediately after the other, those can be arranged only in two following
ways:

Case 1) Mon Tues Wed Thu Fri
J K M N L
Case2) Mon Tues Wed Thurs Fri

L J K M N

On the basis of above two arrangements, we see that J is unloaded either on Monday or Tuesday
