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.

81. Which is the correct combination of first names and surnames?

Show Hint

Barla is the only five-star college, and Techno being higher-rated than Priya's college forces Priya onto the unique three-star college; work the surnames out from there.

  • Mohan Gupta, Sarah Kumar, Priya Chatterjee
  • Priya Chatterjee, Sarah Sanyal, Jackie Kumar
  • Jackie Sanyal, Swati Reddy, Mohan Gupta
  • Jackie Chatterjee, Priya Reddy, Swati Sanyal
Show Solution

The Correct Option is D

Solution and Explanation

This method starts from the two only-one facts, one five-star college and one three-star college, and lets the ratings pin down the surnames instead of deriving names first.

  1. Mohan Gupta, Sarah Kumar, Priya Chatterjee: Mohan Gupta is correct, and Sarah Kumar turns out correct too, but Priya's real surname is Reddy, since she studies at Anipal Institute, which the clue directly gives to Ms. Reddy, not Chatterjee, so this option fails on its third pairing.
  2. Priya Chatterjee, Sarah Sanyal, Jackie Kumar: Sarah's surname cannot be Sanyal, since the clue states plainly that Sarah's last name was not Sanyal; this option fails right away.
  3. Jackie Sanyal, Swati Reddy, Mohan Gupta: Jackie must study at a four-star college (given), but the Sanyal surname belongs to whoever is at Barla College, which is five star, so Jackie cannot be Sanyal; this option fails.
  4. Jackie Chatterjee, Priya Reddy, Swati Sanyal: Priya Reddy fits, because Priya's college is the three-star one (from the Techno-versus-Priya rating clue), and Ms. Reddy is given directly as the Anipal student, whose college is not five star, so the three-star college is Anipal, making Priya equal to Reddy. Swati Sanyal fits, because once Sarah and Priya's surnames are fixed (not Sanyal, and Reddy), and Jackie is ruled out of the five-star Barla college by the four-star clue, Swati is the only person left who can be Sanyal at Barla. Jackie Chatterjee fits by elimination, since Kumar must go to a female first name other than Swati or Priya, leaving Sarah as Kumar and Jackie as Chatterjee.

All three pairings in the last option check out.

Let's summarize:

  • The unique five-star college (Barla) and unique three-star college (whichever is not Deccan) are the anchor facts that fix Swati at Barla and Priya at the three-star college.
  • Ms. Kumar being female then forces Kumar onto Sarah rather than Jackie, since Jackie is not a Ms. in the puzzle.

So the correct combination of first names and surnames is Jackie Chatterjee, Priya Reddy, Swati Sanyal.

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.
