Could somebody help..

Im trying to find out how my tutor got this answer:

There is a ceramic tile size of 900 wide x 600mm high and each tile cost £84.00

How many tiles will be in a Metre squared?

Apparently the answer is 1.4/m2

I would say he got it incorrectly.
600 mm x 900 mm is 0.6 m x 0.9 m = 0.54 m² for a single tile. Ignoring grout, 1.85 tiles would be required to fill a 1 m² space.

Tiles are actually spaced some distance apart and the gap filled with grout. This distance can be varied but 10-12 mm is typical, very small tiles may use gaps as small as 3-6 mm.

The tile should be considered to have one half the selected gap attached to it on all four sides (or the full gap on two sides) To plan the number of tiles, I would assume dimensions with gap to be 0.610 m x 0.910 m, thus 0.555 m² or 1.8 tiles/m².

To get 1.4 tile/m², a grout gap slightly over 108 mm would be required. While "possible," that would look stupid.
