Answer 1

Answer:(a)-5, (b)-6, (c)-1, (d)-2, (e)-3

Explanation:

For converting a Binary code into Decimal, follow the following steps:

Multiply last digit of the code with 2^0, second last with 2^1 , third from the last with 2^2, fourth from the last with 2^3 and so on....

For example, focus on first code of Column A in the question.

Code is: 1010001

To convert it into Decimal,

It will be like 1*2^6 + 0*2^5 + 1*2^4 + 0*2^3 + 0*2^2 + 0*2^1 + 1*2^0.

Hence, it'll be equal to 81.

Similarly, if the numbers in column B is decimal form of codes in column A, then, correct options are related as

(a)-5, (b)-6, (c)-1, (d)-2, (e)-3, (0)-4

Hope it helped all... :-)
