Total Costs (𝑇𝐶)	4	13	32

"If the total cost function is of the form $𝑇𝐶(𝑄) = 𝑎𝑄^2 + 𝑏𝑄 + 𝑐$ where 𝑎, 𝑏, and 𝑐 are constants, then the value of $𝑇𝐶(𝑄) at 𝑄 = 4$ is (in integer)."

A firm has a production function that is homogenous of degree one given by $𝑄 = 2\sqrt{𝐿𝐾}$, where 𝑄 is quantity, 𝐿 is labour and 𝐾 is capital. The unit price of 𝐿 is Rs. 4 and the unit price of 𝐾 is Rs. 16. Assuming that there is zero fixed cost, the total cost (long run) of producing 10 units of 𝑄 is Rs. (in integer).
