Faf du Plessis' side are presently 13 points behind Virat Kohli's team, who sit on top of the table on 124 points.
However, both the sides will finish on 118 points if South Africa sweep of the series.
Nevertheless, even in that scenario, India will be ranked above South Africa when the points are calculated beyond the decimal point.
In such a situation, India will be on 118.47 points, while South Africa will be on 117.53.
On the flipside, if India win all three Tests in the series, then they will move to 128 points while South Africa will slip to 107 points.
