Compare to other companies Infosys interview process was slightly differing. They conduct totally three rounds for the candidates. First round is aptitude test, the question has taken from math problems, verbal and logical reasoning. Here some solved questions have been given below.

Two and a half artists with 2 and half canvases in two and a half hours can paint two and a half drawings. How many artists are needed for 24 canvases and 24 drawings in 24 hours?

Solution:

2 and half artist have 2 and half canvas hence 1artist for 1 canvas

2 artists can work in 2.5 hr to make 2.5 drawing. This relation can be expressed as,

1 artist: 1.25 hour: 1.25 drawing = 4: 5: 5

The question is to find the number of artists to paint 24 drawings on 24 canvases.

Increasing the values in the ratio 4:5:5 proportionately we can arrive at the answer which is 24 artists.

"Distance and Speed" is another important section where one can expect questions. Let us see a sample question.

2) A thief is capable of running 20kms a day. A policeman who is to catch the thief can run 1km on the first day, 2kms on the 2nd day and so on. Then how long will it take the policeman to catch the thief?

Solution:

Let n be no. of days required by the policeman to catch the thief. Then from the problem definition we can arrive at the equation, 1+2+3....+n = 20*n. The left half of the equation is nothing but the sum of "n" natural numbers. This can be re written using the mathematical formula n (n + 1)/2. Hence the above equation becomes,n (n+1)/2=20*n

On solving the above equation we can get two possible values, either n=0 or n=39. However since n = 0 can be only a theoretical solution, the correct answer would be n = 39. The policeman can catch the thief in 39 days.
