 Note: All projects start in 1997.

Question 1

Which of the following had the least cost per room?


The cost per room equals (total cost)/(total rooms)
To calculate the least cost per room, we have to only check IHCL and Lokhandwala Group. A simple inspection will remove all other companies as they have more cost and lesser rooms than either of the two.

Cost per room of IHCL = 275/600 = 45.83 lakhs
Cost per room of Lokhandwala = 225/536 = 41.97 lakhs.

Hence, the cost per room is least for Lokhandwala Group.
