Logical: Critical Reasoning and Analytical Reasoning – 30 Questions 2. Quantitative Aptitude – 25 Questions 3. Technical Questions – 25 Questions Logical: These questions primarily test the analytical and critical thinking skills of the applicants. It tests the most integral skills of the applicant, the logical consistency in thought, understanding and processing data and making valid conclusions from them, and out of the box thinking. The best part about logical reasoning is that it does not require any learning or prior knowledge. Example: • If the positions of the first ten letters and the last ten letters in the English alphabet are interchanged such as that the first and the seventeenth the second and the eighteenth letters are interchanged and this continues till the tenth letter is interchanged with the twenty-sixth letter, which letter will be the fifth to the right of the twelfth letter from the right after this rearrangement? • There is a 3 digit number.

For e.g.; Fraction, Profit and Loss, Combinations and Permutations, Percentage problems, Ratio, Probability, Allegations and Mixtures, Time and distance, Time and work, Measurements, etc. Example: • A sales person by mistake multiplied a number and got the answer as 3, instead of dividing the number by 3. What is the answer he should have actually got? • A traveler walks a certain distance. Had he gone half a kilometer an hour faster, he would have walked in 4/5 of the time, and had he gone half a kilometer an hour slower, he would have walked 2 ½ hours longer. What is the distance? • Two taps A and B fill a tank in 12 and 20 hours respectively and a third tap C empties it in 15 hrs. In how many hours will the tank be filled if the taps A and B are opened simultaneously and C is opened after two hours.?

Example: • An alternate to using interrupts for I/O devices is • The main advantage of using indexes is • PRODUCT Product ID Product Description Manufacturer ID MANUFACTURER Manufacturer ID Manufacturer Name Referring to the above table, what type of relationship exists between the Product table and the Manufacturer table?  Once a candidate clears the written test they will be considered for the second round.
