Answer the questions based on the following information.

Ghosh Babu has a manufacturing unit. The following graph gives the cost for the various number of units. Given: Profit = Revenue - Variable cost - Fixed cost. The fixed cost remains constant up to 34 units after which additional investment is to be done in fixed assets. In any case, production cannot exceed 50 units.

Note: The fixed cost for upto 34 units is 50 and the the fixed cost for more is 100.

The revenue from 50 units is 1000 and the variable cost from 50 units is 700

Question 21
