If Convent college won 6000 from second rankers, then how much money did Aurobindo college win from 3rd rankers?
The number of 2nd rankers from Convent = 3
Hence number of 2nd rankers from Aurobindo = 4 or 3 or 2
But is number of 2nd rankers from Aurobindo is 4 then total money won by Aurobindo becomes
greater than 24000 which contradicts the data given.
The number of 3rd rankers from is either 0 or 2.
