If u have 20 co audits and 8 pvt co ltd audits .. den u can opt for 2 pvt ltd audit only whose psc is less than 100crs.. So the limit for holding audit excluding pvt, small, dormant, one person is 20 co.. and while holding pvt co audit as well, the limit shall be 30 !!
@ Harshit You mean to say an auditor can take maximum of 20 "public companies" (whether listed or unlisted) and 10 private companies (whose paid up share capital is more than Rs 100 crores)?
