Answer:
Option C is correct
The ratio of green to red marbles is, 3 : 1
Explanation:
As per the statement:
A bag contains 44 marbles, some red and some green.
⇒Total marbles = 44
If there are 11 red marbles.
then;
Green marbles = Total marbles - red marbles.
Substitute the given values we have;
Green marbles = 44 - 11 = 33
We have to find the ratio of green to red marbles.

Therefore, the ratio of green to red marbles is, 3 : 1
