Home » Microprocessor » Advanced Microprocessors » Question

(177)8 + 1 = (x)₈, the value of x is—

1. 178
2. 179
3. 200
4. none of these

Correct Option: C

Given (177)₈ + 1 = (x)₈
⇒ 1× 8² + 7 × 8¹ + 7 × 8⁰ + 1
⇒ 64 + 56 + 7 + 1
⇒ 128
Now, we will calculate (128)₁₀ in octal

i.e., (128)₁₀ = (200)₁₀
Hence alternative (C) is the correct choice.
