ITPEC IP October 2020 Question 72
ITPEC IP October 2020 — Question 72 of 100
The required raw-material input for Component Y is 1,000 kg. Producing 300 units of X requires 300 × 3 = 900 completed Y components. With a 90% yield, input A must satisfy A × 0.90 = 900, so A = 900 ÷ 0.90 = 1,000 kg.
Answer (d)
Why not others:
- 900 is the required number of completed Y components, not input before yield loss
- 225 and 250 do not satisfy three Y components per finished X
- Component Z's 50% yield and 600 kg confirm its separate requirement but do not change Y's calculation
Key rule: Required input = required good output ÷ yield rate.
