ITPEC IP October 2019 Question 7
ITPEC IP October 2019 — Question 7 of 100
The right-hand unit outputs 3 as B1. The left unit receives 15 and 6, so it outputs B1 = 6 and B2 = 15 mod 6 = 3. These become the right unit's A1 and A2. Because each unit copies A2 to B1, the final B1 is 3.
Answer (b)
Why not others:
- 0 is the right unit's remainder output because 6 mod 3 = 0, not its B1
- 6 is the first unit's B1
- 15 is an original input and is not copied directly to the final B1
Key rule: Evaluate connected processing blocks from left to right and map every output explicitly to the next block's corresponding input.
