Madhya Pradesh Police Exam Model Paper 3

Given:
Number of days taken by 45 men to dig a pond = 25 days
Concept used:
Total work = Number of men × Time taken
Calculation:
Total work = (45 × 25) units
Number of men required to dig it in 15 days $=\left(45\times 25\right)/15$ men
⇒ 75 men
∴ The number of men to be employed is 75
