## Computer Awareness Quiz: Set – 7 1.The binary system with base 2 will have two digits to represent all numbers 0 and 1.The ternary system with base 3 will have three digits to represent all numbers 0, 1 and 2. In this case numbers will be converted to decimal by multiplying with appropriate powers of 3 eg. 102 = 1*32 + 0*31 + 2*30 = 11.

What will be the result of an addition of (1112)3 and (212)4?
A. (1033)2
B. (1033)4
C. (1303)4
D. (1003)5
E. (1003)4

2. In binary,
0 – 0 = 0, borrow = 0
1 – 0 = 1, borrow = 0
0 – 1 = 1, borrow = 1
1 – 1 = 0, borrow = 0
1 – 1 – 1 = 1, borrow = 1

A number can be converted from binary to decimal as:
10010 = 1*24 + 0*23 + 0*22 + 1*21 + 0*20 = 18

Hexadecimal numbers are written like decimal numbers from 0 to 9. And then 10 is represented as A,11 as B, 12 as C and so on till 15 as F. A binary number can be written into its hexadecimal form by taking 4 digits at a time and then writing its hexadecimal equivalent. For hexadecimal base is 16 like (x)16. Eg the hexadecimal equivalent of 1100 =12 =C and that of 00111110 = (4E)16, Octal representation of 001111=(17)8

What will be the result of hexadecimal subtraction of DA and A8?
A. (30)16
B. (22)16
C. (35)16
D. (34)16
E. (32)16

3. A number can be converted from binary to decimal as:
10010 = 1*24 + 0*23 + 0*22 + 1*21 + 0*20 = 18

An octal number as represented with base 8. What is the octal representation of (BD8)16?

A. (5370)8
B. (5780)8
C. (5730)8
D. (6730)8
E. (5770)8

C. (5730)8

B represents 11 and 11 is coded as (1011)2
Similarly, the code for D is (1101)2 and 8 is (1000)2
BD8 = 101111011000
For octal representation, take 3 digits at a time
101 111 011 000 = (5730)8

4. In binary,
0 + 0 = 0, carry = 0
1 + 0 = 1, carry = 0
0 + 1 = 1, carry = 0
1 + 1 = 0, carry = 1
1 + 1 + 1 = 1, carry = 1
A number can be converted from binary to decimal as:
10001 = 1*24 + 0*23 + 0*22 + 0*21 + 1*20 = 17
What will be the result of binary average of 11011 and 10011?

A. (43)10
B. (24)10
C. (23)10
D. (46)10
E.  (47)10

C. (23)10

1 1 0 1 1 + 1 0 0 1 1 = 1 0 1 1 1 0
The code for 101101 will be = 1*25 + 0*24 + 1*23 + 1*22 + 1*21 + 0*20 = (46)10
Average = 46/2 = 23
