Answer is Right!
Answer is Wrong!
The correct answer is (a) 6.
To solve this, we can use the following formula:
Number of trucks = Total weight / Weight per truck / Number of days
In this case, we have:
Total weight = 540 tons
Weight per truck = 3 tons
Number of days = 30 days
Therefore, the number of trucks is:
Number of trucks = 540 tons / 3 tons per truck / 30 days = 6 trucks
Option (b) is incorrect because 5 trucks would only be able to carry 150 tons in 30 days. Option (c) is incorrect because 4 trucks would only be able to carry 120 tons in 30 days. Option (d) is incorrect because 3 trucks would only be able to carry 90 tons in 30 days.
