There are a number of books on a shelf. If one book is the 4th from the left and 6th from the right, how many books are on the shelf?

One is to three as three is to five and five is to four and four is the magic number.
What is the pattern?

What is full of holes but still holds water?

The more you take me, the more you leave me behind.
Who Am I?

I know a ten-letter word in the English language which can be typed using only the top rows of the computer keyboard.

Jack was having a candle light dinner with his girlfriend. Suddenly a cold gush of wind entered through the open window and three of the ten candles were extinguished. Assuming that none of the other candles were extinguished.

How many candles are they left with in the end ?

Chocolate costs 6 rupees and a Toy costs 5 rupees. If you have 32 rupees in total, how many chocolates and how many Toys can be purchased with that amount?

As easy as you can get into me, it is as hard to get out of me.

Do you know what I am?

Jack have ten pairs of black socks, eight pairs of white socks and seven pairs of green socks. Everything is mixed in a draw. As there is no light he were not able to identify the colour of the socks. How many of the socks did he want to take to match one pair

By using all numbers, i.e. 123456789 and subtraction/addition, operators number 100 can be formed in many ways.
Example: 98 + 7 + 6 - 5 - 4 - 3 + 2 - 1 = 100

But if we add a condition use of the number 32 is a must. Then there are limited solutions.
One of such solution is: 9 - 8 + 76 + 54 - 32 + 1 = 100

Can you tell me any other solution?
