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?

Oh.. sorry.:o
Its 27th of that month.
Re: which day of the month is my birthday ?
yes; 27 is the answer.
folllow the rule:
N(N+1)=2*total sum
Re: which day of the month is my birthday ?
Jainbrijesh and Barbie both of them correct...
The formula is n(n+1)/2(sum of first n numbers) = 378
