    Post XAT 2009: DI and QA Questions

    well after wrong questions in cat 2006 where i was lucky enough not to encounter them

    xat gave one the arrogant and overconfident odds in favour questions

    wasted 5 mins on it seeing that it is very easy and could not find any answer...

    i think it should be 20. u have counted 0333, 0666, 0999, and the ques says "exactly 3 consecutive digits being same", so 9999 should not be such no. which has 4 consecutive digits. And u missed 9000
    so 24 - 5 + 1 = 20
    the options were 12, 16, 19, 21, NOT
    by mistake u got the right answer i.e. NOT
