A process unit involves 3 chemical components. How many mass balances can be written? Correct Answer 4

We can write 4 balance equations: A total balance equation and 3 component balance equations. Independent balances: Not all balances are independent since the total balance is the sum of all of the component balances. Thus, the number of independent balances we can write = the number of components.

A small and medium enterprise imports two components A and B from Taiwan and China respectively and assembles them with other components to form a toy. Components A contributes to 10% of production cost while components B contributes to 20% of production cost. Usually the company sells this toy at 20% above the production cost. Due to increase in the raw material and labour cost in both the countries ,component A became 20% costlier and components B became 40% costlier. Owing to these reasons the company increased its selling price by 15%. Considering that cost of other components does not change.
