ITPEC FE Morning April 2021 — Question 54 of 80
Given: Duration = 2.5 × person-months^(1/3), total = 4096 person-months.
- •
4096^(1/3)= cube root of 4096 =16(since16 × 16 × 16 = 4096) - •
Duration = 2.5 × 16 = 40
Why not others:
- (a) 16 — only the cube root, missing the 2.5 multiplier
- (c) 64 — confuses cube root with square root (64² = 4096)
- (d) 160 — wrong multiplier (×10 instead of ×2.5)
Key rule: COCOMO duration ≈ 2.5 × (person-months)^(1/3). Exam values are chosen so the cube root is a clean integer.
