3 Marks
ANSWER: 24 WAYS

Keeping 1 and 6 fixed, 3 and 5 can be arranged in two ways; similarly 2 and 4 can be arranged in two ways. Therefore 4 ways, interchanging 1 and 6 another 4 ways are possible. Total of 8 ways are possible keeping 1 and 6 fixed.
Similarly keeping 3 and 5 fixed another 8 ways are possible.
Similarly keeping 2 and 4 fixed another 8 ways are possible.

Therefore totally 8+8+8=24 ways are possible.
