Five workers finish a job in 12 days. At the same rate, how long would 8 workers take?
Answer and explanation
Correct answer: B. 7.5 days
Answer: 7.5 days. Why not the others: 19.2 days treats more workers as slower; 7 and 8 are rounded guesses.
- Step 1: Total work: 5 x 12 = 60 worker-days.
- Step 2: Days for 8 workers: 60 / 8 = 7.5.
