Answer:
Correct Answer: B
Solution:
- Let the first number be x.
$ \therefore $ $ x+x+2+x+4+x+6+x+8=220 $
$ \Rightarrow $ $ 5x=220-20=200 $
$ \Rightarrow $ $ x=40 $ Second lowest number of different set $ =40\times 2-37=43 $ Then, five consecutive numbers are 41, 43, 45, 47 and 49.
$ \therefore $ Their sum $ =41+43+45+47+49=225 $
