Hello my friends, I need help with a question for project management.

The city of Mumbai applies a real MARR of 5% on similar past projects. Assuming the same rate can be applied here, calculate the minimum feasible salvage value for each of the options. Consider the inflation rate will remain the same as over the last five years, when CPI rose from 124.6 to 137.4.

Thank you
