Answer the questions on the basis of the information given below.A long thin strip of paper is 256 units in length, 1 unit in width, and is divided into 256 unit squares. The strip of paper is kept in such a manner that the longer side is in the left-right orientation. The squares are numbered 1 through 256 starting from the left most square. The paper is folded into half repeatedly. For the first fold, the right end of the paper is folded over to coincide with and lie on top of the left end. Then the paper is cut at the fold. There are now two strips of paper 1 × 128 in dimensions. Next, the right end of these two strips together is folded over to coincide with and lie on top of the left end, resulting in 4 strips of paper 1 × 64 in dimention. The strip is again cut at the folds. This process is repeated till it becomes a stack of 256 unit squares.What is the number written on the square that is at the 128th position from the bottom?

1) 3
2) 4
3) 128
4) 129
5) None of these
