If four letters are different, then with each letter there
are two possibilities, i.e. A letter can be posted in either
of two mailboxes.
Total no. of ways = 2^4 = 16.

Answer / binesh
I think the robbins way
is right. But i couldnt
under stand why did
he multiply the result
by 2
the chances are
none in the fist box
and all in the other
box=4C0=1
1 in fist and 3 in
second=4C1=4
2 in first and 2 in
second=4C2=6
3 in first and 1 in
second=4C3=4
4 in fist and none in
second=4C4=1
so net chance is
4C0+4C1+4C2+4C3+4C4=16

Answer / lester
If the letters are thought to be unique than the answer is: 2*2*2*2=8
If the letters are thought to be identical(as in spam mails) than the answer is:
(5,0,0) (4,1,0) (3,2,0) (2,3,0) (1,4,0) (0,5,0)
(4,0,1) (3,1,1) (2,2,1) (1,3,1) (0,4,1)
(3,0,2) (2,1,2) (1,2,2) (0,3,2)
(2,0,3) (1,1,3) (0,2,3)
(1,0,4) (0,1,4)
(0,0,5)
1+2+3+4+5+6 = 21 ways

Answer / karthika
Assume 1st box 4 letter and 2nd box no letter,
1st box 1 letter and 2nd box 3 letter,
1st box 2 letter and 2nd box 2 letter,
1st box 3 letter and 2nd box 1 letter,
1st box not post and 2nd box 4 letter,
1st box 3 letter and 2nd box 1 letter,
so totally 6ways

Seven members sat around a table for three days for a conference. The member's names were Abhishek, Amol, Ankur, Anurag, Bhuwan ,Vasu and Vikram. The meetings were chaired by Vikram. On the first evening members sat around the table alphabetically. On the following two nights, Vikram arranged the seating so that he could have Abhishek as near to him as possible and absent minded Vasu as far away as he could. On no evening did any person have sitting next to him a person who had previously been his neighbor. How did Vikram manage to seat everybody to the best advantage on the second and third evenings?
