Spring_2011_CS302_01_Solution_By_VU

Problem Statement:

 

1)    Convert 10101100 binary numbers to its decimal equivalent. (2 Marks)

 

Solution:

 

10101100 = 1x2⁷ + 0x2⁶ + 1x2⁵ + 0x2⁴ + 1x2³+ 1x2² + 0x2¹ + 0x2⁰

    = 1x128 + 0x64 + 1x32+ 0x16 + 1x8 + 1x4 + 0x2 + 0x1

    = 128+0+32+0+8+4+0+0

    = 172

 

2)    Convert decimal number 374 to octal number. (2 Marks)

 

Solution:

 

 

We will use repeated division method.

 

8	374
8	46 – 6
8	5 – 6
	0 - 5

 

Now writing the reminders in the reverse order 566.

 

3)    Convert the following 0110100000111001 (BCD) in to decimal number. (2 Marks)

 

Solution:

We first of all with will write 0110100000111001 in the groups of four bits, and then will write down the decimal equivalent of each group.

 

= 0110 1000 0011 1001

     6      8       3       9

        

Our required decimal number is 6839

 

4)    Convert B2A₁₆ to Octal (2 Marks)

Solution:

First we will convert B2A to Binary

 

1011 0010 1010

 

Now grouping into 3 bit

 

101 100 101 010

 5      4     5    2

 

We will get  5452

 

5)    Convert decimal number 3085 to hex

Solution:

 

 

16	3085
16	192 – 13
16	12 – 0
16	0 – 12

 

 

 

 

 

 

 

12   0   13

C       0      D

 

We will get C0D₁₆
