vipul kumar  (8 years ago)

Ans : 20
Exp: Think from basics..
if total seats N = 5 in a circular arrangement ( _ _ M _ _ M ) where first ( _ ) is connected with last Man(M), then min no of persons required= 2.
similarly If N = 9, Man required = 3 i.e,( _ _ M _ _ M _ _ M )

If N= 12, Man required = 4 i.e, ( _ _ M _ _ M _ _ M _ _ M)
have u got any relation??
the no of man required is = Total no of seats in circle / 3
So, A/Q total seat = 60. Man required = 60/3=20 Ans.

20 will be the ans
the max gap diff between 2 person allowed is 2.
so if you stretch the round table into a line the figure will look like _ _ man _ _ man _ _ man _ _ man...
so its clear that in each 3 seats there will be one man so ans will be 60/3=20
