1:

First says that Total cost = 3 times the material cost
So let material cost be X
total be 3x

so labour cost will be 2x

But now way to find the profits
insuff

2. now it says that profit is greater than the labour cost ...

no way to find the profit still

together
Let k be a factor of x ( profit

3x + kx = 500000 ( k > 2 given)

so Profit will be ( k/(k+3) * 5000000 )

for k = 2 2/5 * 500000
200000
since we have taken the least value of k ...

any other value of k surely will have a larger value..
so profit is always greater than 150000

Hence IMO C
