Study the following information carefully and answer the questions.
For a room, the rate of painting is Rs. 3200 per square metre. The rate of carpeting per square metre is 120% of that of tiling. The cost of decorating the room Is 14 times to that of carpeting on the floor. The cost of electrification is 75% of that of carpeting the floor. The rate of tiling on the floor is 125% of that of painting. The dimensions of the room are 6 m x 6m x 5m.
What will be the total cost of carpeting, decoration, electrification and tiling the floor if the rate of painting be doubled ?
Cost per square metre
Rate of painting = 6400
Rate of tiling = $$\frac{125}{100} * 6400$$ = 8000
Rate of carpeting = $$\frac{120}{100} * 8000$$ = 9600
Rate of decorating = 14 * 9600 = 134400
Rate of electrification = $$\frac{75}{100} * 9600$$ = 7200
Now, total cost :
Carpeting = 6 * 6 * 9600 = Rs. 345600
Decoration = 6 * 6 * 134400 = Rs. 4838400
Electrification = 6 * 6 * 7200 = Rs. 259200
Tiling = 6 * 6 * 8000 = Rs. 288000
$$\therefore$$ total cost = 345600 + 4838400 + 259200 + 288000 = Rs. 5731200
