Here's one approach:
Let a, b, c, d, and e be the first 5 consecutive integers, which means a + b + c + d + e = 560

Here's a unique way to list all 10 consecutive integers: a, b, c, d, e, a+5, b+5, c+5, d+5, e+5 [We can see that e is 4 greater than a, which means the number after e must be 5 greater than a, and so on]

So, the sum of the last 5 integers = (a+5) + (b+5) + (c+5) + (d+5) + (e+5)
= a + b + c + d + e + 25
= 560 + 25
= 585

Answer: A
