ITPEC IP April 2021 Question 55
ITPEC IP April 2021 — Question 55 of 100
The projected cost exceeds the budget by 4.5 million yen. Forty programs cost 15 million yen, so at the same pace the estimated total cost for 60 is 15 × 60 ÷ 40 = 22.5 million yen. Compared with the 18-million-yen budget, the excess is 22.5 − 18 = 4.5 million yen.
Answer (b)
Why not others:
- the other values do not extrapolate the observed cost per completed program to all 60 programs
Key rule: With equal-sized work units and unchanged productivity, forecast total cost from actual cost per completed unit.
