I agree with Himalayan, the answer is A
The reason that it is not B as from A, if the materials costed three times less that the total
so 3x = 500,000
so the materials costed, (500,000/3) = 166000, which means that the profit could not be more than 150,000, hence the question is answered

Stmt 2: is insufficient as it says that the cost of labor was less than the profit, so in this case could e like 50,000(assume) which does not suggest anything about the cost of materials

(C)

formula : Revenue = Costs + Profit

Costs = 500.000 = Labor + Material = L + M.

(1) L+M = 3M = 500.000, then L = 333.000
not suff

(2) P > L
not suff

(1) + (2) P > L = 333.000. got it. (C)

(2) The company’s profit was greater than its cost for labor.

C.

Set L=Labor Cost, M=Material Cost
The question is asking if
500,000 - L - M > 150,000
L + M < 350,000

(1) L + M = 3M
L = 2M
We can pick value for L and M that makes L+M less or greater than 350,000
INSUFFICIENT

(2) 500,000 - L - M > L
2L + M < 500,000
Say L = 1, M = 250,000, which makes L + M less than 350,000
Say L = 1, M = 400,000, which makes L + M more than 350,000
INSUFFICIENT

Together, you have L = 2M
So the question is really asking if:
3M < 350,000
M < 116,666

Plug L=2M in (2), you get
5M < 500,000
M < 100,000
SUFFICIENT

Project Amount = 500000
Total Cost = t
Labour Cost = l
Material Cost = m
t = l+m
Profit = 500000 - t

1) t = 3m
=> 3m = l+m
=> 2m = l
Not sufficient

2)
Profit > l or Profit > 2m
Not sufficient

Combining Profit = 500000 - 3m > 2m
=> 500000 > 5m
=> 100000 > m
=> m < 100000
=> l < 200000
=> m+l < 300000
Profit = 500000 - 300000 = 200000 (Minimum), which is more than 150000.

So Answer is C.

a) The company's total cost was three times its cost for material.
b) The company's profit was greater than its cost for labor.

1. TC = LC + MC; 300,000 = LC + MC
TC = 3MC
LC = 2MC

2. Profit = 500,000 - TC

Combining
say 150,000 = 5000,000 - 3MC
MC = 350,000/3 = approx 113,000
LC = approx 226,000
Hence profit has to be greater than 150,000 since LC = 2MC and Profit > LC

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.

Ans is C

I will denote total cost by C, Material cost by m, Labor cost by l and profit by P

stmt 1: C = 3m = m+l

thus L = 2m....... not sufficient

stmt 2: P>L....... not sufficient

combine: 500000 - C = P

500000 - 3m > 2m......... (ie, P > L)

m < 100000

so 3m or C < 300000

Thus P > 200000
