ans is 32. but both pls provide expln as to how you came at the ans.
for eg . why is it 8c1 and not 8c3 etc etc.
the detailed working is preferred
= Select any person from 8 members(8C1 ways) * select another person (exclude the spouse of previous person) 6C1 * select third person from the remaining(exclude spouses of first and second persons) 4C1 / 3!
F1F2F3 -- can be arranged in 3! ways
F1F2F3 - F2F1F3 - F1F3F2 - F2F3F1 -F3F1F2 - F3F2F1 .. (all these are same)
