Krishnan, did you mean 500,000 in place of 50,000?

With 500,000 I got C as the answer.

From stmt1 alone no idea of profit is available.
From stmt2 alone, no idea of total cost is available.

Combining two, c = cost, l = labor cost, m = material cost.
Then, c = m + l = 3m
or, l = 2m.

Also, 500,000 - c > l
or, 500, 000 > c + l
or, 500,000 > 5m
or, m < 100,000
and l < 200, 000
Hence, c < 300, 000
and profit > 200, 000.
