00:01 Hi, this is a question based on registers.

00:03 So registers we are given with the value of ds as it is 1000 h, ss is given as 2000 h and we have es is given as 3000 h.

00:11 We are given with the value of dx as 4000 h, si is 5000 h and di is 6000 h and we have bp is equal to 7000 h.

00:21 So these are the given values.

00:23 Now for the first case we have mov ax, dx here the effective address for the instruction of the content is dx register that is equal to 4000 h and we have for the second case mov ax, dx plus di.

00:37 So here this is equal to so it is dx and di that is equal to 4000 plus 600 that is a000 h.

00:44 Then we have for third question we have mov bx si.

00:49 So here we have the answer as 5000 h.

00:51 Then we have mov bx bp plus di plus 5.

00:57 So that can be given by.

00:58 So this is 7000 plus 6000 plus 5, doo5 h.

01:02 Then we have for the fifth case mov cx bp.

01:06 So here we have the answer as 7000 h.

01:09 Then for sixth case we have mov ah bx plus 10 h which is equal to so 4010 h.

01:18 Then for seventh case we have mov cx ds bp plus 4.

01:23 So that will be 7000 plus 4 which is equal to 7400 h.

01:27 Then we have for eighth case we have mov bh...
