Dear SajjadAhmad,

I'm happy to respond. :-)

As I am sure you understand, this is relatively easy question. We know from the prompt that the blocks are cubes. That's important.

Statement #1 alone: we know the size of the cubes but not the size of the box. Insufficient.
Statement #2 alone: we know the size of the box but not the size of the cubes. Insufficient.

Combined: we know the exact size of the cubes and of the box, so we can calculate exactly how many cubes go into the box. We don't need to do the calculation. We have sufficient information.

OA = (C)

Does all this make sense?
Mike :-)

Easy one
Statement 1: alone cannot give us the answer because by knowing the dimension of a cube we cannot tell the actual number of that fit into a box.
Statement 2: is also not sufficient to answer because by knowing the dimension of we cannot tell the actual no of cubes that fit into the box so knowing dimensions of the cube is necessary.
On combining S1 and S2, we get the dimensions of cube and box and hence both statements together are sufficient to answer the question
Hence C is the Answer
