Question

Write the number 210 as a sum of three numbers so that the sum of the products taken two at a time is a maximum. (enter the three numbers as a comma-separated list.)

Answer 1

The best answer for this question would be 70, 70, 70. This is because the question does not specify which two numbers will be taken to create the maximum. If, for example it was known that the first two numbers would be added, we would do better with 105, 105, 0 as the first two numbers would then add up to 210.
