Answer:
Weights are 358 and 10 tons
Step-by-step explanation:
Sum and difference problems are made up of the sum or difference of two numbers, one larger than the other.
The larger number equals (sum+difference)/2, and the smaller, (sum-difference)/2.
It is possible that the numbers be negative, so calculate with attention to the signs.
Sum = 368
Difference = 348
Larger value = (sum+difference)/2 = (368+348)/2 = 358
Smaller value = (sum-difference)/2 = (368-348)/2 = 10
Check:
358 + 10 = 368 Ok
358-10 = 348 Ok
Note: the numbers do not sound realistic. Please check carefully the numbers given in the question.
