Solution 25) The shape of each individual curve reflects: B) increasing returns, followed by diminishing returns. Shape of each individual curve shows that first firm faces the increasing return in short run and then if firm keeps on adding the output, then average cost would start incrasing or diminishing return would be seen. 26) The position of these five curves in relation to one another reflects: A) economies and diseconomies of scale.

2. Solution
25) The shape of each individual curve reflects:
B) increasing returns, followed by diminishing returns.
Shape of each individual curve shows that first firm faces the increasing return in short
run and then if firm keeps on adding the output, then average cost would start incrasing or
diminishing return would be seen.
26) The position of these five curves in relation to one another reflects:
A) economies and diseconomies of scale.
Different curves shows the economies and diseconomics of scale since in the long run, firm
would face the increasing cost if it increases the output beyond the capacity.
27) If in the long run the firm should produce output 0x, it should do so with a plant of size:
C) #2.
Average cost is minimum when firm goes with second plant hence correct option is (C)
