Since I cannot tell where the indents (spaces) in the code are, there are two possible answers.
If the "while" part of the code looks like this, with a space before both the second and third line:
while (c < 10):
c = c + 2
sum = sum + c
the answer is 35.
If the "while" part of the code looks like this, with space only before the second line:
while (c < 10):
c = c + 2
sum = sum + c
the answer is 11.
