ITPEC IP April 2023 Question 57
ITPEC IP April 2023 — Question 57 of 100
The projected labor cost is 15 million yen, so the budget excess is 5 million yen. Six million yen produced 40% of the deliverables. At unchanged productivity, total cost is 6 ÷ 0.40 = 15 million yen. Compared with the 10-million-yen budget, the excess is 15 − 10 = 5 million yen.
Answer (d)
Why not others:
- (a), (b), and (c) underestimate the cost required for the remaining 60% at the observed cost efficiency
- elapsed time alone does not change the calculation because the question says productivity remains the same
Key rule: Forecast final cost from actual cost divided by completed fraction, then subtract the original budget to find overrun.
