Marginal product of worker is the net addition to the total product by the employment of an additional unit of worker. Marginal product of worker can be calculated by dividing the change in total product with the change in number of workers employed. MPL= ∆TP/ ∆L. Total product when 3^rd worker employed is total product at 2^nd worker plus marginal product of the 3^rd worker. Marginal product of 4^th worker is change in total product(198-134=64) divided by the change in the number of worker(4-3=1).

Answer: Marginal produce of 4^th worker is 64.
