Question:medium

After execution of ANI 0FH with accumulator = A9H, which flags are affected ?

Show Hint

Logical instructions (AND, OR, XOR) always clear the Carry and Auxiliary Carry flags (though 8085 is an exception for AC). Sign, Zero, and Parity always reflect the result.

Updated On: Jun 6, 2026

Sign, zero and carry
Carry and zero
Zero and parity
Sign, zero, parity and carry

Match List I with List II.

List I	List II
A. Supervisor mode	I. Entered when the processor encounters a software interrupt instruction
B. Abort Mode	II. Entered in response to memory fault
C. Fast Interrupt Mode	III. Entered whenever the processor receives an interrupt signal from a designated fast interrupt source
D. Interrupt Mode	IV. Entered whenever the processor receives an interrupt signal from any other source

Production Theory

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:

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
