Riddle Answer

Saving Time

Our man Ostap was going home from Kiev. He rode halfway by train – fifteen times as fast as he goes on foot. The second half he went by ox team. He can walk twice as fast as that. Would he have saved time if he had gone all the way on foot? If so, by how much?

Answer

Yes. He took as much time for the second half of his trip as the whole trip would have taken on foot.

So no matter how fast the train was, he lost exactly as much time as he spent on the train. He would have saved 130 of the time by walking all the way.

Broken Eggs

A boy was carrying a basket of eggs. He fell down and all the eggs broke. When he went back home without any eggs his mother asked how many he had been carrying altogether in the basket. He was unable to remember.

But he was able to recall that when they were counted two at a time one was left, when counted three at a time one was left, when counted four at a time one was left, when counted five at a time none were left.

Can you tell how many eggs were broken?
