The short-run production function for a firm is as follows
Q = -L³ + 15L² + 10L
Where Q denotes total output in physical units and L denotes units of labour which are homogeneous, but are not perfectly divisible and change in labour does not tend to become zero.
Statement I In this production function, the marginal product of 5^th unit of labour is 85.
Statement II Similarly, in this production function, the average product of the 5^th unit of labour is 60.
