ITPEC IP October 2018 Question 88
ITPEC IP October 2018 — Question 88 of 100
Six staff members per day are required for the remaining 15 days. Total work is 2*5+2*5+3*10+2*5+5*10=110 person-days. One person working for the first 20 days completes 20 person-days, leaving 90. Since 35-20=15 days remain, 90/15=6.
Answer (c)
Why not others:
- four or five staff provide only 60 or 75 person-days and cannot finish
- seven staff would finish but is not the minimum
Key rule: Convert every activity into person-days, subtract completed effort, and divide the remainder by available days when productivity is interchangeable.
