It can be 1 1 4 type or 1 2 3 type distribution. 1 1 4 can be arranged in 3 ways and 1 2 3 in 6 ways. So 9 ways. Since they are different books, we can arrange them in 6! ways. But 6! * 9 = 6480 :p 0 votes 0 votes Ismail commented Jan 20, 2018 reply Follow Share Nope... Answer is 540 0 votes 0 votes Please log in or register to add a comment.
