F is kept immediately above G. A is kept immediately above C. Only E is kept above B. Only two boxes are kept above F. A is not kept at third position from the bottom.
How many boxes are kept above C?
Problem Analysis
The question asks for the number of boxes stacked above box C based on a set of conditions regarding the arrangement of seven boxes (A, B, C, D, E, F, G).
Constraints and Deductions
- Seven boxes are arranged vertically: A, B, C, D, E, F, G.
- Condition 1: F is immediately above G (FG block).
- Condition 2: A is immediately above C (AC block).
- Condition 3: Only E is kept above B. This implies E is the topmost box (Position 1) and B is the second box (Position 2).
- Condition 4: Only two boxes are kept above F. This places F at Position 3.
- Condition 5: A is not kept at the third position from the bottom (Position 5).
Determining the Box Order
Based on the deductions:
- From Condition 3, the top two positions are E and B: E B _ _ _ _ _
- From Condition 4, F is at Position 3: E B F _ _ _ _
- From Condition 1 (FG block), G must be at Position 4: E B F G _ _ _
- The remaining boxes are A, C, and D for positions 5, 6, and 7.
- The AC block (Condition 2) must fit into the remaining slots.
- Possibility 1: AC block at positions 5 and 6. Order: E B F G A C D. This places A at Position 5.
- Possibility 2: AC block at positions 6 and 7. Order: E B F G D A C. This places A at Position 6.
- Condition 5 states A cannot be at Position 5 (third from the bottom). Therefore, Possibility 1 is invalid.
- Possibility 2 is the only valid arrangement: E B F G D A C.
The final order from top to bottom is: E, B, F, G, D, A, C.
Calculating Boxes Above C
Box C is at the bottom (Position 7).
The boxes above C are E, B, F, G, D, and A.
There are 6 boxes above C.
