There are 2 cops parked along a one-way street looking for traffic violations. They spot a taxi driver going in the wrong direction, yet they do nothing.

Why?

A patient was diagnosed with some ailment. He was given five different tablets to take at night at an interval of 15 minutes.

How long will it take the patient to consume all the five tablets?

I am a ten letters word
The first four letters have the power to rule,
Next, four-letter can be eaten.
The next three-letter represents a lady.
I can fly as well

what am I looking for?

What 4-letter word can be written forward, backward or upside down, and can still be read from left to right?

Living above a star, I do not burn
Eleven friends and they do not turn
I can just be visited in a sequence, not once or repeatedly
PQRS are my initials
Can you tell my name accurately?

The more it dries, the wetter it becomes. Can you tell what it is?

How can you leave a room with two legs and return with six legs?

What is so fragile that saying its name breaks it?

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

What do you answer even though it never asks you questions?
