I’m light as a feather, yet the strongest person can’t hold me for five minutes. What am I?

You throw me out when you want to use me and you take me in when you don't want to use me.

Who Am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What is it?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

You may enter, but you may not come in. I have space, but no room. I have keys, but open no lock. What am I?

Seven Robbers robbed a bank and hide the coins in a lonely place.
They decide to divide the money equally the next morning. Two greedy robbers decided to cheat the others and reach the place at night. They equally divided the coins between them, one coin left. So they called another robber and then they decided to divide equally among the three. Sadly again one coin left. The same thing happened to the 4th 5th and the 6th robber.
However, when the 7th robber reached in the morning, they can divide the coins equally.

How many coins were there in total?
