RELIANCE (RIL) PAPER ON 23rd MARCH AT KOLKATA
The reliance paper of 23rd march 2008 was more or less of an easy type. It
had two sections, a mental aptitude test containing 75 questions and a
technical portion of 50 questions. Both were to be solved in half an hour.
Mental aptitude(75 ques):
All of the questions were quite easy, very easy in fact. Just one question
seemed odd, which was:
Revolution is related to evolution in the same way as flying is to
walking/standing/bird/whirling.
Technical(Instrumentation-50 ques):
1 gm/cc = ____kg/m3.
1 atm = ___kg/cm2.
what range of pressure used in pneumatic systems(ans: 3-15 psi).
what type of orifice used for gas-liquid mixture flow:
concentric/segmental/eccentric.

the RAM is irretrievably lost/data is retained/data is retained with minor
modifications/chip is damaged.
if a 20 MHz wave is fed into a cascade of mod-10,mod-5 and mod-4 counters
the lowest o/p freq obtainable is___.
for a tank containing water to a ht. of 2m pressure at the bottom in kg/cm²
