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 decorating the room and tiling the floor when the four walls have also been tiled to a height of 0.25 metre ?

Solution
Cost per square metre,
Rate of painting = 3200
Rate of tiling = $\frac{125}{100} * 3200$ = 4000
Rate of carpeting = $\frac{120}{100} * 4000$ = 4800
Rate of decorating = 14 * 4800 = 67200
Area of tiles on the walls = 2 * 0.25 * (6 + 6) = 6 sq. metre
Area of the floor = 6 * 6 = 36 sq. metre
Cost of decorating = 36 * 67200 = Rs. 2419200
Cost of tiling = (36 + 6) * 4000 = Rs. 168000
$\therefore$ Total cost = 2419200 + 168000 = Rs. 2587200

Solution
Cost per square metre,
Rate of painting = 3200
Rate of tiling = $\frac{125}{100} * 3200$ = 4000
Rate of carpeting = $\frac{120}{100} * 4000$ = 4800
Rate of decorating = 14 * 4800 = 67200
Area of tiles on the walls = 2 * 0.25 * (6 + 6) = 6 sq. metre
Area of the floor = 6 * 6 = 36 sq. metre
Cost of decorating = 36 * 67200 = Rs. 2419200
Cost of tiling = (36 + 6) * 4000 = Rs. 168000
$\therefore$ Total cost = 2419200 + 168000 = Rs. 2587200
