Want to the check how the examiner derived the answer below as in the answer scripts:-
Construction Cost Cost increase per $100m x (3 x 0.9091 + 6 x 0.8264 + 1 x 0.7513) = $ 122.1m I get 82.81. Is it typo error or i get wrongly? Please enlighten.
What it is saying is that the discounted cashflows from 2012 (300 x 0.9091), 2013 (600 x 0.8264) and 2014 (100 x 0.7513) gives a NPV of $122.1m. So cashflows of 84.37 = NPV of 122.1
How much have these cashflows got to change before the NPV = 0
