(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 = $\frac{60}{6}=10Labour(iii)R=\text{(}\frac{48-36}{4-3}$
$\frac{12}{12}$ = 1
(iv) S = $\frac{60-60}{6-5}=\frac{0}{1}$ = 0
(v) T = $\frac{56-60}{8-7}$ = \frac{-4}{1}\) = -4

(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
