    which day of the month is my birthday ?

    As my birthday approaches I start to collect leaves - a little bizarre perhaps, but I enjoy it! On the first day of the month I collect one leaf, on the second day I collect two and so on. So by my birthday I will have collected 378 leaves altogether. On which day of the month is my birthday?

    yes; 27 is the answer.

    Jainbrijesh and Barbie both of them correct...


    The formula is n(n+1)/2(sum of first n numbers) = 378
