Question

6 tractors take 10 days to collect the harvest. How long would it take 10 tractors to do the same work?

Answer 1

6 days

Explanation:

Relation :

• Number of tractors ∝ 1/Number of days

6 tractors took 10 days. Now, we have 10 tractors. This means the number of tractors has increased by 10/6 = 5/3. Therefore, the number of days will become 3/5 of the original time.

Solving :

• 10 × 3/5
• 2 × 3
• 6 days

Answer 2

6 days
If you take -1 each day you get 6 days
