Answer:
The hexadecimal equivalent of the encrypted A is C2
Explanation:
Given
Encrypted binary digit of A = 11000010
Required
Hexadecimal equivalent of the encrypted binary digit.
We start by grouping 11000010 in 4 bits
This is as follows;
1100 0010
The we write down the hexadecimal equivalent of each groupings
1100 is equivalent to 12 in hexadecimal
So, 1100 = 12 = C
0010 is represented by 2 in hexadecimal
So, 0010 = 2
Writing this result together; this gives
1100 0010 = C2
Going through the conversion process;
A is first converted to binary digits by shifting a point to the left
A => 11000010
11000010 is then converted to hexadecimal
11000010 = C2
Conclusively, the hexadecimal equivalent of the encrypted A is C2
Answer:
=IF((D5="Yes"),(C4*1.05),C4)
Explanation:
If condition accepts 3 parameters, where the 1st parameter is the condition and second parameter is the one which needs to be executed “if the condition is true” and the third argument is executed when the “condition is false”.
Here the condition is if there is an delivery ie. D5 = yes, then we add some amount of additional charges through the formula (c4*1.05) and if not we retain the base price C4.
Here the additional delivery charges are considered as 5%. You can change the number according to your need.
