List of top Logical Reasoning Questions asked in Xavier Aptitude Test

A teacher is administering a high-difficulty, multiple-choice quiz to a class of sixty students. The quiz consists of sixty questions, each with six answer choices. The students are seated in ten rows and six columns.

The students are categorized into three groups based on their academic ability, with varying probabilities of selecting the correct answer:

Brilliant students: Have a 0.25 probability of answering a question correctly.
Good students: Have a 0.2 probability of answering a question correctly.
Poor students: Are described as having "no learning advantage," which implies their probability of selecting the correct answer is based on chance (1 in 6).

The teacher is unable to monitor the students during the quiz due to a lack of time and resources, raising concerns about potential cheating.

There is a lot of interest in the first five ranks for Class XI students. One student guessed the rank order as Ankita, Bhagyashree, Chanchal, Devroopa and Esha.

Another student guessed Devroopa, Ankita, Esha, Chanchal and Bhagyashree. Even his guess was wrong. It was found that he had got two positions correct, and two students in his ranking correctly followed their immediate predecessors. Which of the following is true about the correct rank order?

In calendar year 2008, there was turbulence in the air as Jet Airways' Chairman pondered what course of action the airline should take. Air India was also struggling with the same dilemma. Two of India’s largest airlines, Air India and Jet Airways, had sounded caution on their fiscal health due to mounting operational costs. A daily operational loss of 2 million USD (Rs 8.6 crore) had in fact forced Jet Airways to put its employees on alert. Jet’s senior General Manager had termed the situation as grave. Jet’s current losses were 2 million USD a day (including JetLite). The current rate of Jet Airways’ domestic losses was 0.5 million USD (Rs 2.15 crore) and that of JetLite was another 0.5 million. International business was losing over 1 million USD (Rs 4.30 crore) a day.

The situation was equally grave for other national carriers. Driven by mounting losses of almost Rs 10 crore a day, Air India, in its merged avatar, was considering severe cost cutting measures like slashing employee allowances, reducing in-flight catering expenses on short haul flights and restructuring functional arms. The airline also considered other options like cutting maintenance costs by stationing officers at hubs, instead of allowing them to travel at regular intervals.

Jet Airways, Air India and other domestic airlines had reasons to get worried, as 24 airlines across the world had gone bankrupt in the year on account of rising fuel costs. In India, operating costs had gone up 30-40%. Fuel prices had doubled in the past one year to Rs 70,000 per kilolitre, forcing airlines to increase fares. Consequently, passenger load had fallen to an average 55-60% per flight from previous year’s peak of 70-75%. Other airlines faced a similar situation; some were even looking for buyers. Domestic carriers had lost around Rs 4,000 crore in 2007-08 with Air India leading the pack. “As against 27% wage bill globally, our wage bill is 22% of total input costs. Even then we are at a loss," an Air India official said. Civil aviation ministry, however, had a different take: “Air India engineers go to Dubai every fortnight to work for 15 days and stay in five star hotels. If they are stationed there, the airline would save Rs 8 crore a year. This is just the tip of the iceberg. There are several things we can do to reduce operational inefficiency.” According to analysts, Jet Airways could be looking at a combined annual loss of around Rs 3,000 crore, if there were no improvement in operational efficiencies and ATF prices. Against this backdrop, the airline had asked its employees to raise the service bar and arrest falling passenger load.

Analyse the following passage and provide an appropriate answer to the questions that follow.

Silver is especially and repetitively savage about what he sees as the extravagant claims made for particle physics, arguing that once the proton, neutron, and electron were found and their properties experimentally confirmed, the very expensive searches for ever more exotic particles, such as the Higgs Boson, were increasingly harder to justify other than by their importance to particle physicists. Most of the particles resemble ecstatic happiness: They are very short-lived and have nothing to do with everyday life. His repeated assault goes to the level of sarcasm: “Finding the Higgs Boson will be a magnificent technical and theoretical triumph. Like a great Bobby Fisher game.” Of course, this is a tad unfair, even if some of the claims of its practitioners invite such assaults on their field.

What was Sheela’s word?

“The increase in the number of reality shows on television channels bolsters the contention that channel owners are more interested in boosting their revenues by pandering to voyeuristic tendencies of viewers.” The premise behind the above argument is that

“Unlike other retail outlets, where items are purchased in any number of units the customer wants, in super-markets items are grouped in bulk packages.

The option to buy at wholesale prices by buying in bulk makes super-markets a practical choice for budget-conscious consumers.” Which of the following is an assumption necessary to the author’s argument?

“Indigestion? Acidity? Unable to sleep?... Don’t spend the time tossing and turning! Take Magix for a sound, restful sleep … you’ll soon fall asleep, and wake up refreshed and energized. Remember … Magix when you are suffering from acidity and need that sleep!”
