Luis Garavito killed Density x Volume.

Who is Luis Garavito ?

A man is found dead in his bathroom naked with blood scattered all around him. The bathroom was locked from the inside and there is no trace of any struggle. There is nothing in the bathroom except his pant with the belt still around and his shirt. Also, the medic team can't find any incision in his body that may have been the reason behind so much blood loss.

The Police department is clueless regarding this murder mystery.
Can you?

It walks on 4 when its young, walks on 2 when it's older, and walks on 3 when its very old?

You have a thousand Re. 1 coins with you. You have ten bags with you and you can put any number of coins in each of the bags. The condition is that if someone asks you for any amount between 1 and 1000, you must be able to give that amount by just giving the bag (you are not allowed to open the bag and give coins).

How will you do it?

When can we add 2 to 11 and get 1 as the correct answer?

Double it and multiply it by 4. Then divide it by 8 and you’ll have it once more. What number is it?

What is both possible and impossible at the same time?

What does this simple rebus mean?

I have a hole in my back and legs I lack.

Take away the whole and some still remain. What is it?
