This is an intelligent question, involving your lateral thinking. This question was asked in a MNC interview for a top post.  There are 10 crows picking up grain on a floor. One is killed with a banging pistol sound. How many would remain? Choose the answer from the following four:  A. None.  B. One.  C. Nine.  D. May be one or more than one. Answer: The correct answer is “One or more than one”. All the crows fly away on hearing the pistol sound, but ‘Zero’ is not the correct answer, as one dead crow would be there because the birds are on a floor. At this stage, ‘one’ appears to be a correct answer. But never leave anything to escape logic. There may be some deaf crows. You may argue that those deaf birds may also fly-away noticing other crows. They can be both deaf and blind also. With this inference, the conclusion is: one or more than would be there. Among the 4 given answers, this is the most logical one.

Now, first batsman edges the ball to take a single and it hits the helmet. So he scores 6 runs (5+1). On next delivery, it will be the other batsman facing with 1 run to win from 1 ball. he can hit a six to complete his century as well. 2.First ball, the batsman take three runs (with one short run ) and followed by a overthrow boundary. So he scores 6(4+2). Next ball, other batsman hits a clean six to get to his century. Though both of the scenario is highly unlikely to occur, the later one is almost impossible as a overthrow boundary is not easy when one is throwing the ball close to boundary (since they had ran for three, the ball had traveled some distance).
