If mouse would die exactly after 14 hrs then definitely 1 will be the answer but here the given condition says that mouse will die within 14 hrs.
This question will be solved by set theory.
Total beer bottles = 6
Drinking strategy
Bottle 1 : Mouse 1
Bottle 2 : Mouse 2
Bottle 3 : Mouse 3
bottle 4 : mouse 1 and mouse 2
bottle 5 : mouse 2 and mouse 3
bottle 6 : mouse 3 and mouse 1
On the basis of death of mice set we can decide the poisoned bottle
