A girl was sitting in her hotel room when she heard a knock on the door. She opened the door and found that a man was standing outside.
The man said, "Oh! I am really sorry, I thought this was my room."
He then walked through the corridor to the elevator. The girl did not know the man. She closed her door and called security asking them to apprehend the man.
What made her suspicious of that man? He might have been genuinely mistaken.

If you drop me I’m sure to crack, but give me a smile and I’ll always smile back. What am I?

I am the largest in my family of fifty.
The youngest of our family lives separately from the rest of the family and so do I.
I am regarded as harsh and tough.
I am so large, you cut me in two equal halves,
each half would still be larger than the second largest member of the family.
Who am I?

I cannot talk, but I always reply when spoken to. What am I?

Divide 110 into two parts so that one will be 150 per cent of the other. What are the 2 numbers?

They do not possess flesh or feathers or scales or bone
But still, they are blessed with fingers and thumbs of their own.

Can you find out the missing number in the grid?

Can you name some countries which do not have the alphabet 'A' in them?

I have a hole in my back and legs I lack.
I live where I can’t breathe and I eat without teeth.
What am I?
