    My answers to the Top Interview Questions would be random numbers.

    If I say that 170,000 golf balls can fit a school bus. It will be an answer to be bought. I mean If they ask me to prove my answer correct, I will ask them to prove my answer wrong. There is no possible way of proving these questions. Data, even if present will be based on assumptions, so there will always be a varying point of view.

    Stupid questions!!!! Hope you will take back that word. In Google they don’t see whether you answer correctly. What they see is the approach you take to answer them. Without enough knowledge it hard even to understand what the question is about.. 🙂

      Yes, there Qs are not stupid…these type of Q asked in many consultancy companies….like how many ppl wearing the tie today?…how many ppl carrying the ink pen today?….how will u climb the mount Everest within 24 hours ? how will you pass the elephant from a key hole ? …basically they are checking your approach to solve these kind of problems and thn judge your analytical skills and if you carefully see than these type of Qs are very easy…like in cheated husband Q…in dat vilage wife get to know abt the cheated man but not abt her in dat village men enjoying sex and women dnt share this info with the particular wife so all 100 man are alive and Queens statement is correct that at least one man is unfaithful…….btw its happens only in hypothetical village only coz women talks…and talk very much hihihihihihi.
