Answer:
1310
Explanation:
Because, you have to add the biggest number which is 380, to the second to biggest number which is 360, which will both get you to 740. Then you have to add the 740 to 300 which both gives you 1040 and then last but not least you have to add, 1040 and 270 together which will give you 1310 and that's your answer. :)
