It's not possible to answer this question without the other information in the middle, which you skipped as you copied the question. That information tells us the size of the big tiles, the size of the small tiles, and the size of the room. That's how we figure out how many tiles he needs, and once we know that, we can figure out how much they cost. (You also skipped the cost of the big tiles. We'll need that too.)
To decide which tile is more economical for tiling, one must compare the cost per area covered by each tile type. If the large tiles cover more area for a lower cost per square meter, then they would be the better choice. Additional factors like installation ease and waste should also be considered.
