To Start With. . .

1. Next door to me live four brothers of different heights. Their average height is 74 inches, and the difference in height among the first three men is two inches. The difference between the third and the fourth man is six inches.
Can you tell how tall is each brother? Consider all possible cases.

2. Fifty minutes ago if it was four times as many minutes past three o'clock, how many minutes is it until six o'clock?

3. A family I know has several children. Each boy in this family has as many sisters as brothers but each of the girls has twice as many brothers as sisters. How many brothers and sisters are there?

4.Two identical trains, at the equator start travelling round the world in opposite directions. They start to-gether, run at the same speed and are on different tracks.Which train will wear out its wheel treads first?

5. A common puzzle:
A friend of mine runs a bicycle shop and he narrated to me this following story:
A man, who looked like a tourist, came to his shop one day and bought a bicycle from him for Rs. 350. The cost price of the bicycle was Rs. 300. So my friend was happy that he had made a profit of Rs. 50 on the sale. However, at the time of settling the bill, the tourist offered to pay in travellers cheques as he had no cash money with him. My friend hesitated. He had no arrangements with the banks to encash travellers cheques. But he remembered that the shopkeeper next door had such a provision, and so he took the cheques to his friend next door and got cash from him.
The travellers cheques were all made out for Rs. 100 each and so he had taken four cheques from the tourist totalling to Rs. 400! On encashing them my friend paid back the tourist the balance of Rs. 50.
The tourist happily climbed the bicycle and pedalled away whistling a tune.
However, the next morning my friend's neighbour, who had taken the travellers cheques to the bank, called on him and returning the cheques which had proved value-less demanded the refund of his money. My friend quietly refunded the money to his neighbour and tried to trace the tourist who had given him the bad cheques and taken away his bicycle. But the tourist could not be found.
How much did my friend lose altogether in this un-fortunate transaction?
