April 30 (Reuters) - U.S. industrial conglomerate 3M Co posted a 21% rise in quarterly profit on Tuesday, as price hikes and cost cuts offset the impact from slow sales.

The St. Paul, Minnesota-based company reported an adjusted profit of $2.39 per share for the quarter, compared with an adjusted profit of $1.97 per share, a year earlier. (Reporting by Kannaki Deka in Bengaluru; Editing by Shinjini Ganguli)
