Can someone tell me why the answer is 9

Question

arr = [2, 4, 6]
sum = 0
arr.each do |x|
sum += 3
end

puts sum

#output=9

Answer 1

because it says

"sum += 3" and not "sum += x"

So every iteration, the sum is added by 3, and arr has 3 elements so it means 3 iterations.

sum = 0

LOOP
*- - - start - - - *
sum = 3
sum = 6
sum = 9
*- - - end - - - *

puts sum
>> 9
