Find out a multi-digit number that if multiplied by the number 9 or any of its multiplications products (i.e. 18, 27, 36, 45,..) will result in the multiplication factor repeated (n) number of times.

Replace the question mark with the correct number in below Picture:

Place a mathematical symbol between the numerals 5 and 9 in such a way that the resulting number is greater than 5 but smaller than 9.

Can you think of a smallest +ve number such that if we shuffle the digits of the number, the new number becomes double the original number?

While house hunting in London, I came across a very good leasehold property Discussing the lease the landlady told me:

Find three whole, positive numbers that have the same answer when multiplied together as when added together.

I have two coins.
* One of the coins is a faulty coin having a tail on both sides of it.
* The other coin is a perfect coin (heads on side and tail on other).

I blindfold myself and pick a coin and put the coin on the table. The face of the coin towards the sky is the tail.

What is the probability that another side is also tail?
