ITPEC IP April 2022 Question 3
ITPEC IP April 2022 — Question 3 of 100
The product is binary 110111. Convert to decimal for a quick check: 1011₂ = 8 + 2 + 1 = 11, and 101₂ = 4 + 1 = 5. Their product is 11 × 5 = 55. Decomposing 55 into powers of two gives 32 + 16 + 4 + 2 + 1, so the bits for 32, 16, 8, 4, 2, 1 are 1 1 0 1 1 1, or 110111₂.
Answer (d)
Why not others:
- 1111₂ = 15
- 10000₂ = 16
- 101111₂ = 47
Key rule: Binary multiplication follows ordinary positional arithmetic; conversion to decimal provides a reliable verification.
