Q1: Conversion of a hexadecimal number 3D16 to binary number is

A 1111012

B 1100112

C 110001102

D 1100012

E None of the above

ANS:A - 1111012

The concept is separating 3 and D.

3(in hexadecimal ) = 11 ( in binary),
and A = 10 , B = 11 , C = 12 , D = 13 ( all in hexadecimal).
So D is = 13 (in hexadecimal ) = 1101 ( in binary). Now combine the two binary results: (111101) you will get the final answer.
