What is the cost of production in Rs per tonne for a daily production of 100 tonnes?

Question

A foundry has a fixed daily cost of Rs 50,000 whenever it operates and a variable cost of Rs 800Q, where Q is the daily production in tonnes. What is the cost of production in Rs per tonne for a daily production of 100 tonnes?

Answer 1

$\begin{align*} \text{total production cost} &= 50000+800Q\\ &= 50000+800\times 100\\ &=130000 \end{align*}$

this is a cost for 100 tonnes. So, per ton production cost = $\frac{130000}{100}= 1300$
