exemption case.......

As per the guidelines of ICAI,

That the candidate will be declared to have passed in the said group if he secures in a single attempt a minimum of 40 percent marks in each of the papers and an aggregate of 50 percent marks. For the purpose of arriving at the aggregate as already stated above, 60 percent marks or more secured earlier will also be taken into consideration.

The marks of 60 percent or more secured in one or more papers are carried forward automatically for the immediately next three following examinations.

So complying with above proviso , your friend would get the benefit  and is required to score  min. 40 & aggregate 50 in overall...  so he needs 139 to pass the group..
