Scientist decided to do a study on the population growth of
rabbits. Inside a controlled environment, 1000 rabbits were
placed.
Six months later, there were 1000Z rabbits. At the beginning
of the 3rd year, there were roughly 2828Z rabbits, which was
4 times what the scientists placed in there at the beginning
of the 1st year.
If Z is a positive variable, how many rabbits would be there
at the beginning of the 11th year?
Answer / guest
At the beginning of the 11th year, there would be 1,024,000
rabbits.
At the beginning, there were 1000 rabbits. Also, there were
4000 rabbits at the beginning of third year which is equal
to 2828Z. Thus, Z = 4000/2828 i.e. 1.414 (the square root of 2)
Note that 2828Z can be represented as 2000*Z*Z (Z=1.414),
which can be further simplified as 1000*Z*Z*Z*Z
Also, it is given that at the end of 6 months, there were
1000Z rabbits.
It is clear that the population growth is 1.414 times every
six months i.e. 2 times every year. After N years, the
population would be 1000*(Z^(2N)) i.e. 1000*(2^N)
Thus, at the beginning of the 11th year (i.e. after 10
years), there would be 1000*(2^10) i.e. 1,024,000 rabbits.

Substitute digits for the letters to make the following subtraction problem true. S A N T A - C L A U S ----------------- X M A S Note that the leftmost letter can't be zero in any word. Also, there must be a one-to-one mapping between digits and letters. e.g. if you substitute 3 for the letter M, no other letter can be 3 and all other M in the puzzle must be 3.

Only one of the above 3 statements is true and the corresponding box contains the maximum amount. Can you tell which box contains the maximum amount and how much?
A woman took a certain number of eggs to the market and sold some of them. The next day, through the industry of her hens, the number left over had been doubled, and she sold the same number as the previous day. On the third day the new remainder was tripled, and she sold the same number as before. On the fourth day the remainder was quadrupled, and her sales the same as before. On the fifth day what had been left over were quintupled, yet she sold exactly the same as on all the previous occasions and so disposed of her entire stock. What is the smallest number of eggs she could have taken to market the first day, and how many did she sell daily? Note that the answer is not zero.
