Answer:
B, D and E
Explanation:
To maximize the weight he can carry in his backpack, Hamid should choose the three heaviest interns whose combined weight does not exceed 6 kilograms.
Without knowing the weight of each intern, we cannot give a definitive answer. However, assuming we have the weights of the interns, we can follow these steps:
Sort the interns in descending order based on their weight.
Select the three heaviest interns whose combined weight is less than or equal to 6 kilograms.
If there are multiple sets of three interns with the same combined weight, choose the set with the highest individual weight.
For example, if the weights of the interns are:
Intern A: 2 kilograms
Intern B: 3 kilograms
Intern C: 1 kilogram
Intern D: 4 kilograms
Intern E: 2.5 kilograms
Then, Hamid could choose interns B, D, and E, whose combined weight is 9.5 kilograms, which is less than his maximum carrying capacity of 6 kilograms.
