Little things to make u think..

1)In a contest, four fruits (an apple, a banana, an orange, and a pear) have been placed in four closed boxes (one fruit per box). People may guess which fruit is in which box. 123 people participate in the contest. When the boxes are opened, it turns out that 43 people have guessed none of the fruits correctly, 39 people have guessed one fruit correctly, and 31 people have guessed two fruits correctly.

The Riddle : How many people have guessed three fruits correctly, and how many people have guessed four fruits correctly?

2)A black dog stands in the middle of an intersecton in a town painted black. None of the street lights are working due to a power failure caused by a storm. A car with two broken headlights drives towards the dog but turns in time to avoid hitting him. How could the driver have seen the dog in time?

An old farmer died and left 17 cows to his three sons. In his will, the farmer stated that his oldest son should get 1 / 2 , his middle son should get 1 / 3 , and his youngest son should get 1 / 9 of all the cows. The sons, who did not want to end up with half cows, sat for days trying to figure out how many cows each of them should get.
One day, their neighbour came by to see how they were doing after their father�s death. The three sons told him their problem. After thinking for a while, the neighbour said: �I�ll be right back!� He went away, and when he came back, the three sons could divide the cows according to their father�s will, and in such a way that each of them got a whole number of cows.

The Riddle: What was the neighbor�s solution?
