Answer #1

1)

higher saving does not mean that average real GDP shall rise. Saving and investment are done through two different classes. Hence, motives also tend to be distinct for both groups.

Right Answer is (D)

2)

Returns to scale occurs where all factors of production are variable and changed simultaneously. Decreasing returns to scale implies that increase in inputs would not lead to proportionate rise in output.

Input must be increased more than double.

Right answer is (D)
