A firm should increase investment when Marginal efficiency of capital is greater than i. This is because the present value PV of future returns to capital needs to be higher than the cost of capital, Ck. These variables can be expressed as follows: 
If 1/(x+ 1/(y+ 1/z)) = 13/30, then find x+y+z= ?
The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:
If a +`1/b` = 1 and b +`1/c` =1 , then the value of c +`1/a` is
Find the value x2 + y2, if xy = 13 and x + y = 7.
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If cos(A - B) =√3/2and cot(A + B) = 1/√3, where A - B and A + B are acute angles, then (2A - 3B) is equal to:
