are they with any of these groups
or they have a separate group ?
whether they can be on the forecastle or the after deck
or where?
what is the size of the boat?

1yaar buk mein ye pura question dia hai , main apne aap se condition nai bna sakta dude.... ho sakta hai ki question wrong ho
1check the answer now is it anywhere close ? it can be 96 or 2 * 96 otherwise we have to understand the question clearly
13i think we should take 4 sailors each side.....
1ek taraf jyada hone se now doob jayegi toh nao banane wale ko khud chullu bhar paani mein doob jana chahiye
11The ans:-
The special three can be arranged in 4 places on one side There are 4!ways
Now the two on the other side also have 4 places . Therefore 4!/2!ways
Now there are 3 places remaining and 3 sailors therefore 3! ways
Therefore the total ways are:-
4!*4!/2!*3!
4*3*2*4*3*3*2*1
12*8*9*2
=12*72*2
=12*144
=1728
1naw mat dubao yaar....
rest 3 ko 1-1 kar ke both sides rakh ke p and c kar do...
13Take 3 sailors working on one side and 2 on other side
So there are 2 places left on one side where 2 of 3 others can sit.
L1 R1
L2 R2

so required no. of cases: 3C2*4!*4!=1728
