Question
Four of the following five are alike in a certain way
and form a group. Which of the following does not belong to the group? Study the following information carefully and answer the below questions. Eight persons- A, B, C, D, M, N, O and P are starting their business on different month- March, April, August and November on different dates either 06 or 17 of the month of the year 2020. All the information is not necessarily in the same order. O has started on April 17. Only one person is starting the business between M and N. P has started two persons before D. M has started the business on even numbered date after O. The number of persons starting between B and C is same as between N and D. A has started the business on either November or April. D has started on an odd numbered date. C does not start on even numbered date.Solution
O has started on April 17. M has started the business on even numbered date after O. Only one person is starting the business between M and N. From the above condition, there are three possibilities. 
P has started two persons before D. D has started on an odd numbered date. 
C does not start on an even numbered date. A is starting the business on either November or April. 
The number of persons starting between B and C is same as between N and D. From the above condition, case1 and case3 get eliminated. 
Case2 shows the final arrangement.
