(b) What is the number of white cement bags it must sell to have neither profit nor loss, if the number of grey bags sold is 6,400 bags.​

Answer 1

We are given that a cement company earns a profit of Rs. 8 per bag of white cement sold.

now, company sells 3,000 bags of white cement in a month. So,

Total earn by company is, 3000×8=24,000 Rs

Now, we are also given that a cement company loss of Rs. 5 per bag or grey cement sold.

now company sells 5000 bags of grey cement in a month. So,

Total Loss by company is, 5000×5=25,000 Rs

Now, the lossing parts is greater than the earning part. So company having loss

i.e, 24000−25000=−100<0

So, company having loss of Rs.100
