Answers and Solutions for Cumulative DI for CAT:

Solutions:

1) Answer (A)

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.

2) Answer (C)

For the above answer, the ratio of number of rooms to the cost should be maximum. It is maximum for lokhandwala group which is 536/225 = 2.38

3) Answer (C)

Total cost in 1997 = 250 + 225 = 475 Crores.
These projects were completed in 1998 => Interest for 1 year must be added to the cost.
Interest = $$\frac{475*1*10}{100}$$ = 47.5 Crores
Total Amount = 475 + 47.5 = 522.5 Crores.

4) Answer (A)

Total cost of projects that were completed in 1999 is 275 + 235 + 250 + 300 = Rs 1060 Crores.
Interest for 2 years must also be added to this cost => $$1060(1+(0.1))^2$$ = 1060 * 1.21 = Rs 1282.6 Crores

5) Answer (A)

All the projects are completed by 2000. Hence, we need to add the costs of all the projects.
On adding all the costs we get Rs 1785 Crores.
