Question:medium

Consider the following statements :
A. The quality of waste water is determined on the basis of dissolved oxygen.
B. The BOD test is based on dissolved oxygen.
C. Determination of dissolved oxygen also helps in controlling corrosion.
Choose the correct answer from the options given below:

Show Hint

Remember that while oxygen is necessary for life, it is an "enemy" of metal structures. In wastewater treatment plants, maintaining 2 mg/L of DO is generally ideal for aerobic biological processes.

In an oligopolistic market, firm i and firm j have constant marginal cost = c for an identical good. They compete to set prices Pi and Pj. The demand for total market demand Q, where if \(P_i > P_j\), the demand for firm i is 0. If \(P_i < P_j\), the demand for firm i is Q. If \(P_₁ = P_j\), then they share the market equally and hence the demand for firm i is \(\frac{Q}{2}\). In equilibrium, the prices of firms i and j are:

In the table below, firm 1 and firm 2 can cooperate to share market profits or compete with each other. The figures in the cells represent the profits in crores of INR. They can either cooperate with each other where they share INR 10 crores equally. Alternatively, they can compete, which lowers the market output to INR 4 crores, which they share equally. If one of the firms competes while the other cooperates, the former obtains INR 10 crore of profit while the other makes zero profit. In equilibrium, firm A and firm B should respectively:

Firm 2	Cooperate	Compete
Firm 1	5, 5	0, 10
Compete	10,0	2, 2
