Infosys Placement Paper Puzzles

Here are first puzzles from the document for sample. Download complete document from attachments section below.

1.There is a escalator and 2 persons move down it.A takes 50 steps and B takes 75 steps while the escalator is moving down. Given that the time taken by A to take 1 step is equal to time taken by B to take 3 steps. Find the no. of steps in the escalator while it is staionary.

 

Solution (not sure):

If A takes 1 step in one second, then B takes 3 steps in one second. If A takes t1 seconds to take 50 steps, then B takes 150 steps in t1 seconds.

For B, to take 150 steps he requires t1 seconds,

then to take 75 steps he requires t1/2 seconds.

So now, s1=50, t1 = t1 & s2=75, t2=t1/2

ans= (s1*t2 ~ s2*t1) / (t1 ~ t2) which gives 100.

so 100 steps is the answer

 

2. If 5/2 artists make 5/2 paintings using 5/2 canvases in 5/2 days then how many artists r required to make 25 paintings using 25 canvases in 25 days?

 

3. If the digits of my present age are reversed then i get the age of my son.If 1 year ago my age was twice as that of my son.Find my present age.

hi...im sorry but none of these puzzles are asked anymore in the interviews or the aptitude test..when i went for my recruitement,i had gone through these but it was quite a waste of time as none of these are used now..we just had a simple aptitude test,but the cutoffs are high as most of the people can do them..and then the HR interview in which they ask a variety of questions which may get a little technical too..however, after the HR, some of us were called (those who had mentioned language skills) and there technical interview was taken...which went quite bad..but that was just to scare them..otherwise it depends a lot on ur focus as time is a constraint and english is very important
