(2) H.R. ROUND

Once u clear written Round interview is just a formalty . they ask a few basic puzzles like

1. You are provided 2 candles of equal size, which can burn one hour every. You have

When the first candle will burn out ,then light up the both ends of the second candle
(15+30=45)

3. You r provided a thermometer. What can u do by this without measuring the
temperature?

Ans: if u put thermometer into a tree it won’t grow anymore, will just die off

4. How it is possible to place 4 points that are equidistance from every other?
OR

Ans: Oscillate the hanging bulb. compute the time period for 1 complete
oscillation by Simple Harmonic Motion (SHM) of the handing bulb. Put it in the
