Answer:
Option (c) 8
Explanation:
Data provided in the question:
Marginal rate of technical substitution of hours of labor for hours of capital, RTS = 0.8
Number of units of labor chosen = 5
Number of units of capital chosen = 8
Marginal product of capital = 10 televisions per hour
Now,
RTS = [ Marginal product of labor ] ÷ [ Marginal product of capital ]
0.8 = Marginal product of labor ÷ 10
or
Marginal product of labor = 8
Hence,
Option (c) 8
