Analytical ques

1. You are given with two identical iron bars. one of them is magnetized and the other is not. u are suppose

to find which one is magnetized. u are not suppose to use any other thing.

my ans: first time i told that i will suspend the bars freely. but then they told me that i am not suppose to

use any external help. i took some time and then realized that a magnetic bar in the middle repels

towards the end . i told that place one of the bars horizontal & then move the other one perpendicularly

to it . if it repels towards any of ends then the horizontal one is magnetized if it attracts then is

not. They were convinced

2: What is the result of (x-a)*(x-b)*(x-c)*...........*(x-y)*(x-z) ? my ans: i told that since there is a term (x-x) the

answer is zero. They told ok. finally they asked me whether i have any questions to them i asked them what is

the duration of training and what is field which i will be working on if i get selected.

Anyone looking for infi solve Shakuntala devi's 2 books, George summers and Ravi narula this would me

more than enough. most important thing is develop ur logical analysis skill and try to remember the

approach rather than answers. don’t panic in the interview just be cool and confident u will definitely

get through. Best of luck for all
