Now,

cost + profit = 500,000

cost is divided into 2 parts, material and labour

if material = m, then labour = 2m (from 1)

also profit > 2m (from 2)

therefore,

m + 2m + (greater than 2m) = 500,000 (using both 1 and 2)

now even if u take the least value of profit possible, i.e., 2m, you can see that you get a minimum profit of 200,000. Hence, you can determine whether the profit is greater than 150,000 using both 1 and 2...
