  2. 13.36%

  3. 1.33%

  4. 13.66%

  5. None of these


Correct Option: B
Explanation:

The premises of showroom which are to be renovated are: Reception area, General Manager's room, pantry, service desk and display area. So, total area of the above rooms = Area of (reception + General Manager's room + pantry + service desk + display area) = 1287 sq. m + 621 sq. m + 1368 sq. m + 713 sq. m + 1209 sq. m = 5198 sq. m. But the total area of the car showroom is 6000 sq. m. So, area which is not to be renovated = Total area of the car showroom - total area of the rooms to be renovated = 6000 sq. m - 5198 sq. m = 802 sq. m. Therefore, the percentage area of the showroom not to be renovated = 802 sq. m/6000 sq. m x 100 = 13.36%

  4. 1455440 : 457290

  5. 50724 : 11551


Correct Option: A
Explanation:

Rooms to be floored with marble are: Display area, Service desk and Pantry

Thus, the total cost of marble flooring = Total area of display area + Service desk + Pantry x cost of Marble at Rs. 280 per sq. m = 39 m x 31 m + 31 m x 23 m + 38 m x 36 m x Rs. 280 = 1209 sq. m + 713 sq. m + 1368 sq. m x Rs. 280 = 3290 sq. m x Rs. 280 = Rs. 921200. Rooms to be floored with granite are: General Manager's room and Reception

Thus, the total cost of granite flooring = Total area of General Manager's room + Reception x cost of Granite at Rs. 240 per sq. m = 23 m x 27 m + 33 m x 39 m x Rs. 240 = 1908 sq. m x Rs. 240 = Rs. 457920 Therefore, the ratio will be 921200 : 457920 = 11515 : 5724

  2. Rs. 1266840

  3. Rs. 727720

  4. Rs. 112208

  5. Rs. 112280


Correct Option: E
Explanation:

Remaining area of the showroom = Total area of the showroom - Total area to be renovated = 6000 sq. m - total areas of [Display room + Service Desk + Pantry + General Manager's room + Reception]. = 6000 sq. m - [39m x 31m + 31m x 23m + 38m x 36m + 23m x 27m + 33m x 39m] = 6000 sq. m - 5198 sq. m = 802 sq. m The cost of carpeting the remaining area = Remaining area of the showroom x Cost of carpet at Rs. 140 per sq. m = 802 sq. m x Rs. 140 = Rs. 112280 Therefore, the increment in the total cost of renovation will be Rs. 112280.

  2. Rs. 94740

  3. Rs. 89040

  4. Rs. 841970

  5. Rs. 98160


Correct Option: A
Explanation:

Rooms to be painted with Plastic Paint's are Kitchen and the two bathrooms. Hence, total cost of plastic paint = Paint cost of Kitchen + Paint cost of two bathrooms = Rs.60480 + Rs.100800 = Rs.161280.Rooms to be painted with rich textured emulsion paint's are Master Bedroom, Guest room, Children room, Drawing room and living room. Hence, total cost of rich textured emulsion paint = Paint cost of Master bedroom + Paint cost of Guest room + Paint cost of children room + Paint cost of Drawing room+ Paint cost of living room. = Rs.211680 + Rs.188160 + Rs.164640 + Rs.235200 + Rs.203840 = Rs.1003520.So, the total painting cost of the house = Rs.161280 + Rs.1003520 = Rs.1164800.However, if the entire house it to be painted with rich emulsion paint only then Kitchen and the two bathrooms should also be painted with it, we get; Paint area of Kitchen x Cost of rich textured emulsion at Rs.280 per Sq. m. = 504 Sq.m. x 280 = Rs.141120.and Paint area of two bathrooms x Cost of rich textured emulsion at Rs.280 per Sq. m. = 420 Sq.m. x 280 = Rs.117600.Now the total painting cost of the house = Rs.1003520 + Rs.258720 = Rs.1262240. So, the difference = Rs.1262240 - Rs.1164800 = Rs.97440.

  2. Rs. 547680

  3. Rs. 497280

  4. Rs. 265440

  5. Rs. 493920


Correct Option: B
Explanation:

Bathrooms are attached to master bedroom and drawing room. Total cost of painting = Paint area of a bathroom + Paint area of master bedroom + Paint area of another bathroom + Paint area of drawing room. Paint area of Bathroom = 8 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 7 m x 14 m (Height of the room) x 2 (Two walls of the same size) = 224 sq. m + 196 sq. m = 420 sq. m x Cost of plastic paint at Rs. 120 per sq. m  = Rs. 50400

Painting area of master bedroom = 15 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 12 m x 14 m (Height of the room) x 2 (Two walls of the same size) = 420 sq. m + 336 sq. m = 756 sq. m x Cost of rich textured emulsion at Rs. 280 per sq. m  = Rs. 211680

Painting area of Drawing Bedroom = 15m x 14m(Height of the room) x 4 (Four walls of same size). = 840 sq. m x Cost of rich textured emulsion at Rs. 280 per sq. m  = Rs. 235200. So, total cost = Rs. 50400 x 2 (as two bathroomsare there) + Paint cost of master bedroom + Paint cost of drawing room = Rs. 100800 + Rs. 211680 + Rs. 235200 = Rs. 547680

Paint cost of kitchen = 12 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 6 m x 14 m (Height of the room) x 2 (Two walls of the same size) = 336 sq. m + 168 sq. m = 504 sq. m x Cost of plastic paint at Rs. 120 per sq. m  = Rs. 60480 Paint area of bathroom = 8 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 7 m x 14 m (Height of the room) x 2 (Two walls of the same size). = 224 sq. m + 196 sq. m = 756 sq. m x Cost of plastic paint at Rs. 120 per sq. m  = Rs. 50400 x 2 (as two bathrooms ae there) = Rs. 100800. Hence, total cost of plastic paint = Paint cost of kitchen + Paint cost of two bathrooms = Rs. 60480 + Rs. 100800 = Rs. 161280

Directions: Study the following information and answer the question that follows.

A house is to be constructed which will have a master bedroom, a guest room, a children room, a kitchen, a drawing room, a living room and bathrooms attached to the master bedroom and the drawing room. The height of all the rooms is supposed to be 14 m. The area of the house comprises of the master bedroom measuring 15 m x 12 m, the guest room measuring 12 m x 12 m, the children room measuring 9 m x 12 m, the kitchen measuring 12 m x 6 m, the drawing room measuring 15 m x 15 m, the living room measuring 13 m x 13 m and bathrooms measuring 8 m x 7 m. The rooms, if they have area less than 100 sq. m, are to be painted with plastic paint and floored with vitrified tiles. The rooms with area greater than 100 sq. m are to be painted with rich textured emulsion and floored with marble. The rate of marble flooring is Rs. 300 per sq. m and that of vitrified tiles is Rs. 150 per sq. m. The price of painting with plastic paint is Rs. 120 per sq. m and that with rich textured emulsion is Rs. 280 per sq. m. No ceiling is to be painted unless asked in the question.

  2. Rs. 238680

  3. Rs. 159840

  4. Rs. 265580

  5. Rs. 265680


Correct Option: E
Explanation:

Flooring area of master bedroom = 15 m x 12 m = 180 sq. m x Marble flooring at Rs. 300 per sq. m = Rs. 54000. Painting area of master bedroom = 15 m x 14 m (Height of the room) x 2 (Two walls of the same size) + 12 m x 14 m (Height of the room) x 2 (Two walls of the same size) = 420 sq. m + 336 sq. m = 756 sq. m x Cost of rich textured emulsion at Rs. 280 per sq. m = Rs. 211680 Hence, total cost of flooring and painting = Rs. 54000 + Rs. 211680 = Rs. 265680
