Given two literals 0x001B and 033. What are these equal to?

Question

[A] 21 and 23

[B] 27 and 33

[C] 33 and 33

[D] 27 and 27

Answer & Explanation
Option: [D]

Let us convert the given Hexadecimal number 0x001B to Decimal:

The first part is 0x16⁰=0

The second part is 0x16³+0x16²+1x16¹+11x16⁰ [Though B is equivalent to 11]

=27

So, 0+27=0

Now we convert the octal number 033 to decimal:

0x8²+3x¹+3⁰

=27
