Understanding the Seating Arrangement
To solve the problem, we systematically analyze the statements provided:
Chair Assignments
- Chair 8 is occupied by Rohit (extreme left).
- Hardik is on chair 5.
- Chair 6 is the second from the left.
Row Configuration
- Chairs are numbered 1 to 10, with odd and even chairs not adjacent or opposite to each other.
- Since Rohit is on chair 8 (even), the odd-numbered chairs (1, 3, 5, 7, 9) must be positioned accordingly.
Placement of Cricketers
- Virat sits on an odd chair, not adjacent to Rohit (chair 8).
- Yuvraj occupies an even chair, diagonally opposite chair 1 (farthest from chair 1) - this positions him at chair 10.
Analyzing Chair Relations
- Chairs 4 and 6 are not in the same row as chair 8. Since 6 is already placed, chair 4 must be on the opposite row.
- Suresh and Mahendra sit adjacent to chair 6, but Mahendra cannot be adjacent to chair 4.
Conclusion of Arrangement
- After organizing the above, we find:
- Row 1: 1, 3, 4, 6, 9
- Row 2: 2, 5, 8, 10 (with Rohit at chair 8)
Thus, the correct chair numbers in one of the rows are 1, 3, 4, 6, 9, confirming that option C is indeed the correct answer.

Similar CAT Doubts

The chief scientist of a major vaccine producing company has the responsibility to keep the formula of the vaccine confidential. He stores the formula in his e-device with 3 consecutive locks, all of which need to be unlocked to access the formula. The first of the 3 locks is a pattern lock, the second one is a numeric lock and the third and final one is an alphanumeric lock. The pattern lock is in the form of a regular hexagon with 6 distinct vertices A1, A2, A3, A4, A5, A6, in that order. One needs to connect all the 6 vertices one after the another in any random order connecting each vertex only once and only one order of connecting the 6 vertices exists which will unlock the first lock. The numeric lock has a code of ABC, where A, B and C are single digit natural numbers. A is a multiple of 2. B is a multiple of 3, C is a multiple of 4 but not equal to A.The alphanumeric lock has a code MNPQRS, where M and N are alphabets and P, Q, R and S are digits. M and N have to be consecutive vowels or consecutive consonants, not necessarily in order. Two alphabets are said to be consecutive vowels if both of them are vowels and they are consecutive when all the 5 vowels are written in alphabetical order. For example, E and I are consecutive vowels, but A and O are not. Two alphabets are said to be consecutive consonants if both of them are consonants and they are consecutive when all the 21 consonants are written in alphabetical order. For example, D and F are consecutive consonants but D and V are not. For example, M and N can be A and E respectively or E and A respectively. P is equal to Base-Ten-Index of M. Q is equal to the Base-Ten-Index of N. R and S can only take binary values, that is, 0 or 1.Base-Ten-Index of an alphabet = Index of alphabet % 10, where Index of an alphabet is its position when all alphabets from A to Z are arranged alphabetically and a%b is the remainder when a is divided by b.For example, Base-Ten-Index of J = 10 = 0 , Base-Ten-Index of M = 13 = 3.The chief scientist can only set passwords/patterns which follow all of the conditions mentioned above.Based on the information given above, answer the questions that follow.Q.How many alphanumeric codes for the third lock are possible which necessarily have an A as one of the alphabets in the code?
