I don' think this is easy at all. Ive never seen a combinatorics Q like this before.

Is the answer E? Im stuck btwn D or E, but id vouch for E. I can't really explain it, its just what I got in my notes.

we have 3!/2! * 3!/2! = 9. But i really don't know if this is correct.

If i keep aside all my technical knowledge of P&C, i'll land up with E though the OA is not E

D. 8

x: 0 - 1 - 2 - 3
y: 3 - 2 - 1 - 0

if x = 0, y = 3 => 1 way
if x = 1, y = 2 => 3 ways
if x = 2, y = 1 => 3 ways
if x = 3, y = 0 => 1 way

so total = 8 ways

Case 1: empty, all 3 in one office -> 2 ways
Case 2: 1 employee, 2 employees -> 2 * 3C2 = 6 ways
Total = 8 ways
