ITPEC IP April 2021 Question 53
ITPEC IP April 2021 — Question 53 of 100
Four new members are required. The total work is 6 members × 20 days = 120 standard member-days. In 15 days, the original six complete 6 × 15 = 90, leaving 30. A new member at half productivity contributes 15 × 0.5 = 7.5 standard member-days, so 30 ÷ 7.5 = 4.
Answer (c)
Why not others:
- one or two members provide only 7.5 or 15 additional member-days
- six members would work but are more than the minimum
Key rule: Convert all labor to a common productivity-adjusted member-day unit before calculating headcount.
