Question:medium

Constant reflux ratio maintained during binary mixture batch distillation results in:-

Show Hint

Remember the tradeoff: If $R$ is constant, $x_D$ drops. If you want $x_D$ constant, you must increase $R$ (which increases time and energy costs).

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:

If Y = F(L,K) is a linear homogeneous production function, then multiplying all inputs by a constant factor α = 2 results in output increasing by a factor of:

Production Function

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
