IIITH PGEE 2015 - Paper I - General Aptitude few questions from exam

Check Overview blog post of IIITH PGEE 2015 exam

Calculator was not allowed for this paper. Paper consisted of 45 questions, Time duration: 90 mins

English:
There were 2 passages and each having 5 questions to answer.

Logical Reasoning and Numerical Ability:
- One question on time and work. A little trickier e.g. Few men complete some work in x days, If after 2 days, 'y' men were added, how long will it take to complete the work?


- One question was on water tank filling type e.g. Taps 'A' and 'B' fill tank in x and y minutes. After how much time should tap 'B' be closed so that it takes 30 mins to fill the tank
- A famous question from logic - You visit a place, and 3-way cross road. There are two identical person, one speaks truth, and other always speaks a lie. You don't know which one is speaking truth. When you reach there, there is only 1 person at the roadside. You forgot/don't know, which road leads to which city. You need to ask only 1 question so that you are sure, which way to go. Which question would you ask?
- Another straight question from logic - a logical expression was given, we need to find if it's tautology or not.
- Few C code snippets, playing around with arrays, simple pointers. One question asking, which of the 4 given code snippets has of dangling pointer? (Yes c code snippets were given in General Aptitude paper)
- A recursive C code was given, and we need to find the output if a given number was passed to it.
- One simple arithmetic question about - there are x hens and y dogs in a farm. Total heads and legs are given, you need to find the population. The options were little tricky. You do need to find the exact answer, but need to know more maths to answer them correctly. Multiple options could be correct. e.g. in this problem correct options were 1. number of hens is prime. 2. number of dogs exceed number of hens by x. , etc.
- One question was to identify the next element in given sequence. - I was not able to identify this one. As far as I recall the question was indium vanadium xenon lithium carbon ____?
- There were few others that I couldn't answer - decay life of a element was given and you need to find the amount of element remaining after x number of years.
- There were difficult problems from geometry - 1. you were given equations of some graph and need to find tangent to it with some given conditions. 2. Another problem had a equation of pair of line and it was given that they were revolved around some axis, then find the equation of resulting conic.
- A little twisted numerical question was - there were 999919 mice on a island. you need to find the possible number of cats, if each cat ate same number of mice and each cat ate more mice that the number of cats. It was easy problem, solution to which struck me at last minute. Solution was to just find a number that divides the given number + also being able to divide the remainder in equal number of parts.
- Matrix - Value of determinant was given and it was asked which option is impossible to calculate a) |Ainverse|, b) |Atranspose| - |A| c) |5A| d) 5|A| e) |Atranspose|
