    Certain number of boxes are in a stack, such that the

    box, which is at the bottom, is numbered as 1, the box above it as 2 and so on. Box W is 14th box from the bottom and 38th box from the top. If 23 new boxes are added to the stack, then what is the total number of boxes in the stack?
    A 74 boxes Correct Answer Incorrect Answer
    B 56 boxes Correct Answer Incorrect Answer
    C 86 boxes Correct Answer Incorrect Answer
    D 67 boxes Correct Answer Incorrect Answer

    Solution

    Box W is 14th box from the bottom and 38th box from the top. There are 13 boxes below the box A and 37 boxes above box W. Thus, initially there are 51 boxes (13 + 37 + 1) in the stack. As 23 new boxes are added to the stack, thus there are a total of 74 (51 + 23) boxes in the stack.
