I always drive my customer away.

Who am I?

If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

Usually, a boxing match consists of twelve rounds. In a particular friendly match between two heavyweights, the match was finished in the ninth round itself as one of the boxers knocked out the other one.

But, in that fight, no man threw even a single punch.

How can this be possible?

Many have heard it, but nobody has ever seen it, and it will not speak back until spoken to. What is it?

1 + 9 + 8 = ?
considering, 28 + 8 + 92 = 10

Look at the below sequence of letters and tell us what the next letter should be:

O T T F F S S ?

Use the digits from 1 up to 9 and make 100.

Follow the rules.
=> Each digit should be used only once.
=> You can only use addition.
=> For making a number, two single digits can be combined (for example, 4 and 2 can be combined to form 42 or 24)
=> A fraction can also be made by combining the two single digits (for example, 4 and 2 can be combined to form 4/2 or 2/4)

Question: how can we do this?
