If 6 workers complete a job in 15 days. How many days will 9 workers take assuming the same work rate?
Show answer & explanation
Correct answer: A
Explanation
Work is fixed, so:
Workers × Days = Total Work
6 × 15 = 90
Now for 9 workers:
Days = Total Work ÷ Workers
90 ÷ 9 = 10 days
Hence, the correct option is 1.
