Question

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 didn't study at 'Barla College.' Sarah, whose last name wasn't Sanyal, joined 'Techno Institute.' Ms. Kumar and Jackie both studied at four-star colleges. Ms. Reddy studied at the 'Anipal Institute,' which wasn't a five-star college. The 'Barla College' was a five-star college. Swati's last name wasn't Chatterjee. The 'Chemical College' was rated with one star less than the college where Sanyal studied. Only one college was rated five star.

The person with surname Sanyal was:

• A. Sarah studying in Chemical College
• B. Swati studying in Barla College
• C. Priya studying in Deccan College
• D. Jackie studying in Deccan College

Hint:

Sanyal's college works out to be the five-star Barla College; then eliminate Mohan, Sarah and Priya by name/college, and eliminate Jackie because Jackie's college must be four star, leaving only Swati.

Answer 1

The Correct Option is B

Step 1: Fix which college Sanyal studied at.
As in the companion question, only one college is five star, and Barla College is that one, so Barla is the unique five-star college. Working through the 'Chemical College is one star below Sanyal's college' clue (Chemical cannot itself be three star without creating a second five-star college), Anipal turns out to be the three-star college, Chemical/Deccan/Techno are four star, and Sanyal's college, being one star above Chemical's four stars, has to be the five-star Barla College. So whoever has the surname Sanyal studies at Barla College.

Step 2: Rule out people who cannot be Sanyal.
Mohan's surname is explicitly Gupta, so Mohan is not Sanyal. Sarah's surname is explicitly stated to not be Sanyal. Priya was shown (in the companion question) to study at Anipal Institute, but Sanyal's college is Barla, a different college, so Priya cannot be Sanyal either. That leaves only Swati or Jackie as possible candidates for the surname Sanyal.

Step 3: Use the four-star clue to decide between Swati and Jackie.
We are told Jackie studied at a four-star college. If Jackie were Sanyal, Jackie would have to study at Barla, which is five star, not four star, so that contradicts the clue about Jackie. This rules out Jackie, leaving Swati as the only person who can carry the surname Sanyal.

Step 4: Confirm the answer and rule out the other options.
So Swati Sanyal studies at Barla College, matching the second option exactly. Option A is wrong because Sarah studies at Techno Institute, not Chemical College. Option C is wrong because Priya studies at Anipal Institute, not Deccan College. Option D is wrong because Jackie is not Sanyal at all, as shown in Step 3.

Final Answer:
Swati studying in Barla College. \[ \boxed{\text{Swati, Barla College}} \]
