There are bananas in the fruit shop, and the quality of five kilograms of pears is six times that of bananas. Excuse me, a math problem.
In the remaining five baskets, the quality of pears is twice that of bananas, that is, the quality of pears is three times that of pears. So first add up any five numbers to see if they can be divisible by 3 to get 8+9+16+19+23 = 75 kg, and then see which three numbers add up to be divisible by the sum of the other two numbers.
