Complete the following table.

What will come in place of D?

6

The correct answer is Option 1: 6

Step 1: Calculate Total Product at 3 units (E)

• Given A = 10 (AP at 3 units of labour)
• TP3​=AP3​×Labour3​
• TP3=10*3 = 30

Step 2: Calculate Total Product at 4 units

• Given AP at 4 units = 9
• TP4​=AP4​×Labour4​
• TP4= 9* 4 = 36

Step 3: Find D (MP at 4 units of labour)

               D=MP4​ =TP4​−TP3​

                D= 36-30 = 6
