Answer:
A) Project R = benefit / cost = 20 / 16 = 1.25
Project R with road = benefit / cost = 36 / 24 = 1.50
Project F = benefit / cost = 26 / 20 = 1.30
Project F with road = benefit / cost = 30 / 28 = 1.07
Project W = benefit / cost = 10 / 2 = 5.00
Project W with road = benefit / cost = 8 / 10 = 0.80
Road = benefit / cost = 2 / 8 = 0.25
B) Project W should be selected since its cost benefit ratio is higher than the rest of the alternatives.
Explanation:
The cost benefit ratio is a profitability ratio that helps investors to understand how much money an investment will yield. In case of project W, for each dollar invested, the project will yield $5.
