Given below are two statements:
Statement 1: (167) 10=(10100111)2
Statement II: (11010110) 2=(214)10
In the light of the above statements, choose the correct answer from the options given below
Correct Answer :
Both Statement I and Statement II are true.
Solution :
The correct option is: Both Statement I and Statement II are true.
Let us verify both statements step-by-step to understand why they are correct.
Step 1: Verify Statement I
Statement I claims that the decimal number 167 is equivalent to the binary number 10100111.
To convert the decimal number (167)10 to binary, we divide by 2 repeatedly and record the remainders from bottom to top:
167 �� 2 = 83 with a remainder of 1
83 ÷ 2 = 41 with a remainder of 1
41 ÷ 2 = 20 with a remainder of 1
20 ÷ 2 = 10 with a remainder of 0
10 ÷ 2 = 5 with a remainder of 0
5 ÷ 2 = 2 with a remainder of 1
2 ÷ 2 = 1 with a remainder of 0
1 ÷ 2 = 0 with a remainder of 1
Reading the remainders from bottom to top gives the binary representation:
10100111
Thus, (167)10 = (10100111)2. Statement I is true.
Step 2: Verify Statement II
Statement II claims that the binary number 11010110 is equivalent to the decimal number 214.
To convert the binary number (11010110)2 to decimal, we express it as the sum of powers of 2 multiplied by their corresponding bits:
Calculating the values of the powers of 2:
27 = 128
26 = 64
25 = 32
24 = 16
23 = 8
22 = 4
21 = 2
20 = 1
Substituting these back into the expression:
(1 × 128) + (1 × 64) + (0 × 32) + (1 × 16) + (0 × 8) + (1 × 4) + (1 × 2) + (0 × 1)
= 128 + 64 + 0 + 16 + 0 + 4 + 2 + 0
= 214
Thus, (11010110)2 = (214)10. Statement II is true.
Since both Statement I and Statement II are correct, the correct option is "Both Statement I and Statement II are true."
