Suppose five crates are weighed two at a time in all possible ways. the weights in pounds are 110, 112, 113, 114, 115, 116, 117, 118, 120, and 121. how much does each crate weigh?

**Definitely not impossible lol.**

1) Start by adding all those up.

2) How many times has each crate been included in total? Divide by that number to the sum of all of the 5 weights.

3) What is the sum of the 2 lightest ones? What is the sum of the 2 heaviest ones? Subtract these from the total and you will have the middle weight.

4) Now juggle the numbers until you get the other 4

Hint: the lightest 2 will be 55-alpha, and 55+alpha

Have fun :)
