Pronounced as 1 letter, And written with 3, 2 letters there are, and 2 only in me. I’m double, I’m single, I’m black blue and grey, I’m read from both ends, and the same either way. What am I?

A word I know has six letters it contains, remove one letter and 12 remain. What is it?

What is the probability of getting a sum as 9 of the two numbers shown?

I am thinking of a five-digit number such that:
The first and last digits are the same, their submission is an even number and multiplication is an odd number and is equal to the fourth number. Subtract five from it and we obtain the second number. Then divide into exact halves and we get the 3rd number.

What number I am thinking of?

A sundial has the fewest moving parts of any timepiece. Which has the most?

Where do fish keep their money?

The person who makes it has no need for it; the person who buys it has no use for it. The person who uses it can neither see nor feel it. What is it?

I taste better than I can smell. Who am I?
