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:
