 Kasinath @Hyd said: (Aug 20, 2014) Candidates Appeared in 1996+1997 = 47400. Candidates Qualified in 1996+1997 = Q. Percentage of Qualified to Appeared in 1996+1997 = 60+50 = 110%. Qualified/Appeared = 110%. =>Q/47400 = 110/100. =>Q=(110/100)/47400 = 11*4740. Qualified Students = 52140. Answer is None of the above.
