hi,
the reason there is only one cobra byu statement 2....
if you pick 2 snakes atleast one is viper...
say as u are saying there are two cobra and 8 viper.. then there can be a chance that these two cobras are picked up , but the statement ll tells us atleast one is viper..
so this statement will not be true... but we know this statement is true, so we can have only one cobra..
and when we pick up two snakes it could be two vipers or one viper and one cobra...
hope it helped
Hi chetan2u
Thanks for the reply but am not able to get it
The questions asks the no of cobras right..!!
and for each viper dr is one cobra. Thn dr must be an equal no of both of them. But we cannot sat what's the number.
This is where am confused...!! ?
I know i sound silly but sometimes your are stuck at a point in some questions..![/quote]
hi, the question never tells us that there is one cobra for each viper....
it says there are atleast one cobra and one viper...
so it could be 1 cobra and 10 viper or 1 viper and 10 cobras or 10 viper and 100 cobras....
statement B
the statement ll tells us atleast one is viper..
so for more than one cobra, atleast one viper in two snakes will not stand. it is possible to have both cobra if the cobras are more than 2 ... and this statement will not be true... but we know this statement is true, so we can have only one cobra..and when we pick up two snakes it could be two vipers or one viper and one cobra
