@Jaideep,
Last line is simple as that of first two. Initially she takes 4 i.e. 0100 and in the last line we got 32 which is nothing but 8 x 4 = 32. Thats only the answer that we wanted.

There is no multiplication instruction in the 8085.
These operations are equivalent to multiplying by 2:
1) Shift left by 1 (shifting left by n is multiplying by 2^n).
2) Add the value to itself once.
So 2^3 = 8.
