SECTION C: ANALYTICAL REASONING AND DECISION MAKING

Directions (Question No 74-85): Each group of questions in this section is based on a set of conditions. In answering some of the questions, it may be useful to draw a rough diagram. Choose the response that most accurately and completely answers each question.

Questions (81-85): 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 3 star, all other colleges were rated either 4 star or 5 star.

The “Techno Institute” had a higher rating than 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.
