Answer:
The correct option is;
1
Explanation:
The number of teeth on the blue, driver, gear = 20 T
The number of teeth on the yellow, driven, gear = 20 T
In order to find the gear ratio of a gear train, the ratio of the number of teeth on the driven gear to the number of teeth on the driver gear gives the gear ratio
Therefore, the gear ratio = 20 T/(20 T) = 1
