From the question (31-35)
Seven people M, N, O, P, Q, R and S have an interview on seven different days of the same week, starting from Monday and ending on Sunday, but not necessarily in the same order. Each one of them also likes different subjects namely- Geography, Zoology, Sociology, Mathematics, Hindi, History and Accountancy, but not necessarily in the same order.
Only three people have their interview between N and the one who likes Zoology. N has his interview on one of the days after Tuesday but before Saturday. Only one person has an interview between P and the one who likes Zoology. Only two people have their interview be-tween P and the one who likes Geography. The one who likes Sociology has an interview immediately before the one who likes Geography. The number of people having interview between P and the one who likes Sociology is the same as that of the number of people between and N. The one who likes Hindi has an interview after P but before Q. Only two people have their interview between S and the one who likes Hindi.
The one who likes Accountancy has an interview immediately after M but not on Wednesday, R has an interview on one of the days before the one who likes Mathematics.
Four of the following five are alike in a certain way based on the given arrangement and hence form a group. Which of the following does not belong to the group ?
Correct Answer: (4) O-Hindi
Solution:| Day | Person | Subject |
| Monday | S | Zoology |
| Tuesday | R | History |
| Wednesday | P | Mathematics |
| Thursday | O | Hindi |
| Friday | N | Sociology |
| Saturday | M | Geography |
| Sunday | Q | Accountancy |
Except the combination O- Hindi, all other combinations are mismatched.
The one who likes Mathematics has an interview on Wednesday and Wednesday +3= Saturday.
The one who likes Geography has an interview on Saturday and Saturday −3= Wednesday.
The one who likes Sociology has an interview on Friday and the one who likes History has an interview on Tuesday.
Tuesday +3= Friday.
S has an interview on Monday and Monday +3= Thursday.
