Answer:

5000 rupees

Step-by-step explanation:

Given the following :

Dimension of room = 5m × 2.5m

Cost of granite = 600 rupees per square meter

Cost of marble = 1000 rupees per square meter

Additional cost of using marble instead of granite :

Area of room = Area of rectangle = Length * width

Area of room = 5m × 2.5m = 12.5m^2

Cost of using granite:

Area of room × cost of granite per square meter

12.5 × 600 = 7500 rupees

Cost of using marble:

Area of room × cost of marble per square meter

12.5 × 1000 = 12,500 rupees

Difference in cost :

(12500 - 7500) rupees = 5000 rupees

Additional cost incurred if marble is used = 5000 rupees
