CBSE gives your result of 10th class in CGPA. However shortlisting is done in terms of a unique and universally accepted method of calculating your marks.

10th document conversion is basically another sheet which has to be given by the school which indicated marks conversion form CGPA to percentage by *9.5

Ps: Do not worry if you do not have one. Just submit the original marksheet. It has clear indications on how to convert from percentage to marks.
