    trick question?
    If a time like 01:00 also satisfies the "3 numbers in a row" criteria, then a lot leh... Tired also... cannot count!

    01:00 does not count, they are not in a row .

    basically it's 7 times (IMHO).
    First, let's settle with 4 numbers in a row, we have:

    1. 11:11
    2. 00:00 (if this counts, but.. for analogue clocks, i presume they refer as 12.00AM?)

    Then consider three numbers in a row:

    3. 01:11
    4. 02:22
    5. 03:33
    6. 04:44
    7. 05:55
    8. 10:00

    Then it's analogue clock.. so.. probably you have to count twice the frequency. so.. should be 16 times (incl. of 00:00) or 14 times (excl. of 00:00).

    Hope i'm right. Heh.

    leezacch is very close, this is not militarty time, hence 0:00 is wrong.

    abian, almost there. if you remove the 0:00, look closer.

    41 times??
    ahbian's arguments look very convincing !

    But then again, since it's not military time.. means zeros in the hourly digit(s) are redundant
    Probably it will be:

    1. 12.22 AM
    2. 1.11 AM
    3. 2.22AM
    4. 3.33AM
    5. 4.44AM
    6. 5.55AM
    7. 10.00AM
    8. 11.11AM

    So to get frequency for one course day, multiply the frequency by 2, we will get 16. Haha, same as lightbrush

    Whats that? Aiyah, I thought the prize is a watch.

    I needed one.

    Will donate the prize back to you. You can create another question for others if you really want to give away. Sorry to make you go back to square one.

    you need to say ADJACENT and IN A ROW

    for 01:00 not to count.

    otherwise, on the same line = in the same row.

    Apart from counting, which bit of this question is really maths?
    It is more lateral thinking and english proficiency to me.
