A side of beef lost 35 percent of its weight in processing. If the side of beef weighed 546 pounds after processing, how many pounds did it weigh before processing?

(A) 191

(B) 355

(C) 737

(D) 840

(E) 1,560

Let the weight of the beef before processing be 100 after processing , weight of the beef is 65

When the weight of the beef is 65 (after processing) ; weight of the beef before processing is 100

When the weight of the beef is 1 (after processing) ; weight of the beef before processing is 100/65

When the weight of the beef is 540 (after processing) ; weight of the beef before processing is (100/65)*540 => 840

Hence answer is (D)
