The length, breadth, and height of a rectangular room are 14 ft, 13 ft, and 10 ft respectively. There are two square windows with 3 feet edges and two doors of size 6ft × 3ft in the room.

1. How much does it cost to paint four walls and ceiling of the room excluding doors and windows at the rate of Rs. 36 per square foot? Find it.
2. How much the total cost will increase to paint on the same part if the cost of painting per square meter is increased by one-third of what it was before due to the increase in the market price? Find it.
