Question:hard

Five people joined different engineering colleges. Their first names were Sarah (Ms.), Swati (Ms.), Jackie, Mohan and Priya (Ms.). The surnames were Reddy, Gupta, Sanyal, Kumar and Chatterjee. Except for one college which was rated as 3 star, all other colleges were rated either 4 star or 5 star.

The 'Techno Institute' had a higher rating than the college where Priya studied. The three-star college was not 'Deccan College.' Mohan's last name was Gupta, but he did not study at 'Barla College.' Sarah, whose last name was not Sanyal, joined 'Techno Institute.' Ms. Kumar and Jackie both studied at four-star colleges. Ms. Reddy studied at the 'Anipal Institute,' which was not a five-star college. The 'Barla College' was a five-star college. Swati's last name was not Chatterjee. The 'Chemical College' was rated one star less than the college where Sanyal studied. Only one college was rated five star.

83. Mohan Gupta may have joined:

Show Hint

Mohan is ruled out of Barla, Techno and Anipal by direct clues, and the surname trail places him at Chemical College, which is four star like Deccan and Techno.

  • Techno Institute which had 5 star rating
  • Deccan College which had 5 star rating
  • Anipal Institute which had 4 star rating
  • Chemical College which had 4 star rating
Show Solution

The Correct Option is D

Solution and Explanation

This check goes through the five options directly, using only the ratings and the placements that are already fixed for the other four people.

  1. Techno Institute, 5 star rating: wrong on both counts. Techno is Sarah's college by direct statement, not Mohan's, and Techno is four star, not five star, since Barla is the only five-star college.
  2. Deccan College, 5 star rating: wrong on the rating; Deccan is one of the three four-star colleges (Techno, Deccan, Chemical), since Barla alone is five star.
  3. Anipal Institute, 4 star rating: wrong on the college. Anipal belongs to Priya, who is Ms. Reddy, and it is actually the three-star college, not four star.
  4. Chemical College, 4 star rating: Mohan is ruled out of Barla (direct clue), Techno (Sarah's) and Anipal (Priya's, as Ms. Reddy), leaving only Deccan and Chemical; tracing the surnames through, Swati-Sanyal-Barla, Sarah-Kumar-Techno, Priya-Reddy-Anipal, Jackie-Chatterjee, Mohan-Gupta, places Jackie at Deccan and Mohan at Chemical, and Chemical, like Techno and Deccan, is four star since only Barla is five star and only Anipal is three star.
  5. Techno Institute, 4 star rating: the rating, four star, is correct for Techno, but Techno is Sarah's college, not Mohan's, so this pairing is still wrong for Mohan.

Only Chemical College at four star fits Mohan.

Let's summarize:

  • Mohan is excluded from Barla, Techno and Anipal by direct or derived clues, leaving Deccan and Chemical.
  • Since only Barla is five star and only Anipal is three star, both Deccan and Chemical are four star, and the surname trail (Gupta equals Mohan) settles Chemical as his specific college.

So Mohan Gupta joined Chemical College, rated four star.

Top Questions on Data Arrangement

Questions Asked in XAT exam

Read the scenario and answer the question:
The upper hinge of a dataset is the median of all the values to the right of the median of the dataset in an ascending arrangement, while the lower hinge of the dataset is the median of all the values to the left of the median of the dataset in the same arrangement.
For example, consider the dataset 4, 3, 2, 6, 4, 2, 7. When arranged in the ascending order, it becomes 2, 2, 3, 4, 4, 6, 7. The median is 4 (the bold value), and hence the upper hinge is the median of 4, 6, 7, i.e., 6. Similarly, the lower hinge is 2. 
A student has surveyed thirteen of her teachers, and recorded their work experience (in integer years). Two of the values recorded by the student got smudged, and she cannot recall those values. All she remembers is that those two values were unequal, so let us write them as A and B, where A < B. The remaining eleven values, as recorded, are: 5, 6, 7, 8, 12, 16, 19, 21, 21, 27, 29. Moreover, the student also remembers the following summary measures, calculated based on all the thirteen values: 
Minimum: 2
Lower Hinge: 6.5 
Median: 12 
Upper Hinge: 21 
Maximum: 29

Read the following scenario and answer the questions that follow.
A T20 cricket match consists of two teams playing twenty overs each, numbered 1 to 20. The runs scored in any over is a non-negative integer. The run rate at the end of any over is the average runs scored up to and including that over, i.e., the run rate at the end of the kth over is the average number of runs scored in overs numbered \(1, 2, …, k,\) where \(1 \leq k \leq 20, k\) a positive integer.
The following table indicates the run rate of a team at the end of some of the overs during a T20 cricket match (correct up to 2 decimal places), where \(1 \leq N – 2 < N + 6 \leq 20\), N a positive integer. It is also known that the team did not score less than 6 runs and more than 15 runs in any over.
