Question

\(\begin{array}{c|c} \text{Units of variable factor} & \text{Total Product} \\ \hline 1 & 25 \\ \hline 2 & 31 \\ \hline 3 & 40 \\ \hline 4 & 48 \\ \hline 5 & 55 \\ \end{array}\)

The marginal product at the fifth variable factor is

Options

A)
7
B)
6
C)
5
D)
9

The correct answer is A.

Explanation:

MP = Δ TP ÷ Δ L
= (TP2 – TP1) ÷ L2 – L1
= (55 – 48 ) ÷ (5 – 4) = 7 ÷ 1
= 7
