Final exam exemption doubt

Dear friends,

If a candidate scores 60 or more than 60 in any one of the papers of a group but fails in that group and appears for all papers in that group, he could claim exemption in the paper in which he has scored 60 or more.

My doubt is what is the minimum number of marks he has to obtain in failed papers of that group in order to avail that exemption or whether it is enough that the candidate attends all papers in that group for availing exemption????

Kindly clarify, Thanks in adavnce.
