All the pages of a book starting from page 1 are summed. One of the pages has been added twice, and the total thus obtained is 1000. Which is the page that has been added twice ?
We know that sum of first n natural number is= n(n+1)/2 As one number is added twice , let this number be x then n(n+1)/2 +x=1000 n(n+1)/2 <1000 WE have to calculate n such that n is maximum and n(n+1)/2<1000n2+ n-2000<0 we will get n=44For n=44Sum= 44*45/2=990Repeated number=1000-990=10
