Question

If 00000111 in a register is shifted to read 00111000, the arithmetic operation is
a) X2
b) X4
c) X16
d) X8​

Answer 1

Answer:

The correct answer is (d) X8.

Step-by-step explanation:

The digits are represented in the binary system( having only 0s and 1s).

Each shift to the left refers to a multiplication by 2, however, in this case, there are 3 such shifts and hence it is multiplied by 2^3 = 8 ( or in other words, it is multiplied by 1000- in a binary system).

[ In the decimal system it is 8, in the binary system it is 1000].
