(1) The company's total cost was three times its cost for materials.
(2) The company's profit was greater than its cost for labor.

This question is from GMATPrep. I've amended the quote above to reflect the true wording of the question.

Let L = Labor, M = Materials.
Total Cost = L+M.

To make the math easier:
Let Revenue = 500, Desired Profit = 150.

Actual Profit = Revenue - Cost = 500 - (L+M).

For the Actual Profit to be greater than the Desired Profit of 150:
500 - (L+M) > 150.
L + M < 350.

Question rephrased: Is the total cost of L+M < 350?

Statement 1: Total Cost=3M.
L+M = 3M
L=2M.
No way to determine whether L+M<350.
Insufficient.

Statement 2: The profit was greater than its cost for labor.
500 - (L+M) > L
500 - L - M > L
2L+M < 500.
No way to determine whether L+M<350.

Statements 1 and 2 combined: L=2M and 2L+M<500.
Substituting L=2M into 2L+M<500, we get:
2(2M) + M < 500.
5M < 500.
M < 100.

Since M<100, and Total Cost=3M, we know that Total Cost < 300.
Sufficient.

The correct answer is C.

this is not GMAT problem as the question contains undefined terminology costs, total costs, profit
BUT the most logical to advance here would be
st(a) Total Cost=Materials+Labor, 3*Materials=Materials+Labor <> 2*Materials=Labor, and this isn't sufficient to find profit which is (logically) 500,000-Total Costs, as we don't know neither Profit/Total Costs nor quantities of Labor, Materials
st(b) Profit>Labor, not sufficient, as we don't know the Labor
Combined st(a&b): still not sufficient as we don't know quantities of Labor, Materials

I would effectively ignore the source of such problems
