Question 1
If 15 workers can complete a job in 24 days, how many workers are needed to complete it in 9 days?
  • 30
  • 35
  • 40✔️
  • 45
Correct Answer Explanation
Using inverse proportion: \(\text{Workers} \times \text{Days} = \text{constant}\). \(15 \times 24 = x \times 9\). \(x = \dfrac{15 \times 24}{9} = \dfrac{360}{9} = 40\) workers.
