Your Answer is

Correct Answer is H

Explanation

To calculate the number of small trucks, you need to subtract the cargo volume of large trucks first, so 83000-2×18000=47000, and the number of condensers that need to be transported by small trucks is 47000. Divide the number of condensers that need to be transported by a small truck, 47,000, by the maximum cargo volume of each small truck, 7,000, that is, 47,000÷7000=6.71. The answer is in fractions, showing that six pickup trucks can't quite move all the condensers. There isn't enough cargo left to fill a pick-up truck, but one is still needed. Therefore, a total of seven pick-up trucks are required. Choose H.
