Answer / guest
Number 3 is face down on the table.
If Abu can see two even numbers i.e. number 2 twice, and if
Dabu can see number 2 twice, then number 2 must be facing up.
Now everything else is simple. (see the following diagram)
Dabu Abu
1
3 2 2
1
Calu Babu
Thus, the number hidden from the view is number 3 and hence
the answer.
