Explanation

(a)(i) Total product = Average product x Units of labour
36 = P x 3,   P3 = 36 P = 36
P= \(\frac{36}{3}\) = 12

(ii) Q = Total product    = \(\frac{60}{6}  = 10 
               Labour

(iii) R = \(\frac{48-36}{4-3}\)
\(\frac{12}{12}\) = 1

(iv) S = \(\frac{60 - 60}{6 - 5} = \frac{0}{1}\) = 0

(v) T = \(\frac{56 - 60}{8 - 7}\) = \frac{-4}{1}\) = -4

Variable units of labour Fixed Assets (Hecteres of Land) Total Product (kg) Average Product (kg) Marginal product (kg)
1 3 8 8 -
2 3 18 9 10
3 3 36 P 18
4 3 48 12 12
5 3 55 11 7
6 3 60 10 5
7 3 60 8.6 0
8 3 56 7 -4

(c) Both TP and MP rise initially. The TP curve is at maxi-mum when MP is zero. 
TP declines after MP = 0 and MP assumes negative values
At N6 = 400 - 150 = 250 units

(c) Excess supply at prices N8, N9 and N10 .
Excess supplied at N8 = 400 - 250 = 150 units 
                          at N9 = 500 - 150 = 350units
                          at N10 = 600 - 50 =550 units 

(d) At price N7, Quantity is 300 units
