I want to present a series of brain teaser problems collected from
various sources, for the benefit of the members looking for some
tougher-level questions. Here it goes the first one.....
1. There are eight bags of rice looking alike, seven of which have
equal weight and one is slightly heavier. The weighing balance is of
unlimited capacity. Using this balance, the minimum number of
weighings required to identify the heavier bag is
(A) 2 (B) 3 (C) 4 (D) 5 (E) 8
