Direction: Data below represent the number of people required for various projects to be completed in various days: Project Situation 1 Situation 2 Number of workers Days required Number of workers Days required A X 88 X+8 66 B Y Y-1 Y+6 Y-6 C Z2 75 M2 108 |
| 1) | 60 days | 2) | 80 days |
| 3) | 90 days | 4) | 120 days |
| 5) | None of these | ||
Answer : 90 days
Explanation : Total workers = 0.5Z * 2 M = 0.5 * (1.2 M) * 2 M = 1.2 M2 Total work = M2 * 108 = 1.2 M2 * No of days = > No of days = (M2 * 108) / (1.2 M2 ) = 90 days
Explanation : Total workers = 0.5Z * 2 M = 0.5 * (1.2 M) * 2 M = 1.2 M2 Total work = M2 * 108 = 1.2 M2 * No of days = > No of days = (M2 * 108) / (1.2 M2 ) = 90 days

Answer : 33 days
Explanation :
M1 * D1 = M2 * D2
Explanation :
Solutions:
Project A:
X * 88 = (X + 8) * 66
= > 88X = 66X + 8 * 66 = > 22X = 8 * 66 = > X = 24
Project B:
Y * (Y - 1) = (Y + 6) * (Y - 6)
Y2 – Y = Y2 – 62
= > Y = 36
Project C:
Z2 * 75 = M2 * 108
= > Z2 / M2 = 108/75
= > Z2 / M2 = 36/25
= > Z / M = 6/5
= > Z = 6/5 * M
= > Z = 1.2 M
24 * 88 = 64 * D2
= > D2 = (24 * 88)/64
= > D2 = 33 days
