5 crates for a total weight of 5 x 250 = 1250

A) If known crates are heaviest within possible range

2 x 205 = 410
2 x 310 = 620
Total: 1030

5th crate: 1250 - 1030 = 220

B) If known crates are lightest within possible range

2 x 200 = 400
2 x 300 = 620
Total: 1000

5th crate: 1250 - 1000 = 250


--> Range: 220 - 250
