The quarrying cost of marble and granite blocks plus delivery cost to the processing plant each is Php 2,400.00 per cubic meter. Processing cost of marble into tiles is Php 200.00 per square meter and that of granite into tiles also is Php 600.00 per square meter. If marble has a net yield of 40 square meters of tiles per cubic meter of block and sells at Php 400 per square meter, and granite gives a net yield of 50 square meters of tiles per cubic meter of block and sells at Php 1,000 per square meter, determine the more profitable material, considering all other cost to be the same.
