Do you know the answer for this?

(Answer this no longer 5 minutes)

You are standing in the middle boulevard then suddenly a crowd pass to you and then you asked them 'how many are you' but then they ignored you. An hour pass, another bunch of people pass again., then you are confused and then asked them again 'How many are you?. One of the crowd answered, 'We are only half of the first crowd who passed this boulevard!, and then he added, 'But if you will go with us we are now all 100, including the first crowd passed'!..

The simple question is 'What is the exact number of the first crowd passed on that boulevard?'...do not think...lol

33?

I mean 66?

lol..

66.

You and the 2 crowds = 100.

2 crowds = 99

2nd crowd is half of first crowd = 33

First crowd = 66
