Two
workers, A and B, produce 200 pieces each of a product per hour. Because of
defects, 2% of the pieces produced by B are rejected. These defective pieces
are repaired at a cost of ₱ 15.00 per piece. The cost of materials per piece is
₱ 25.00. Both workers are paid ₱ 100 per hour. By how many percent should
worker A’s wage be increased so that the cost per piece of his product will
equal that of worker B?
