Answer: The relationship between A and B project cannot be determined with the information given.
Explanation: The relationship between PW(A) and PW(B) is the correlation between project A and Project B in a portfolio.
This is not possible to be calculated with the information given.
But an expression of calculating this is;
PW is the present value of A and B projects.
MARR is the minimum acceptable rate of return
The calculate the correlation of the two project, divide MARR by the multiple of the two project.
That is;
Correlation = MARR ÷ [PW(A) × PW(B)]
Therefore;
Correlation = i11% ÷ [PW(A) × PW(B)]
This shows that the relationship cannot be determined with the limited Information supplied.
