NATA 2017 ANSWER KEY

 

Hello Friends,

The entrance exam for NATA 2017 was held on 16th April according to the new pattern. The Council of Architecture had not come out with any sample Nata Question Papers, which left Nata Aspirants with a lot of guesswork for the upcoming exams. For the benefit of the Student Community, MOSAIC has come out with the ANSWER KEY for NATA 2017

To Qualify NATA 2017,

  • A candidate should score at least 25% in MCQ's ie. Mathematics & General Aptitude Combined - 30 out of 120
  • A candidate should score at least 25% in Drawing Portion - 20 out of 80
  • Overall qualifying marks ( out of 200 ) would be based on post - exam statistics and at discretion of the Council.

GENERAL APTITUDE TEST

 

Q1. How many bricks of dimension 20 cm X 10 cm X 10 cm are required to build a wall 12 m long, 3m high and 30 cm wide, if 10% of the wall is comprised of mortar?

(A) 4860                                                                                     (B) 5200

(C) 4600                                                                                     (D) 5000

Ans. ( A ) 4860

EXPLANATION: To get the number of bricks used in the wall, we need

                       The volume of brick wall / Volume of a single brick

                       The given dimensions of brick are in cm ie. 20cm X 10cm X 10 cm

                        Volume of a brick = 20 X 10 X 10 = 2000

                       Lets convert the dimensions of the brick wall also in cm

                       Given dimensions for brick wall - 12 m X 3 m X 30 cm

                       Since, 1 metre = 100 cm

                       Therefore, brick wall dimensions in cm are 1200cm X 300cm X 30 cm

                       So, Volume of brick wall = 1200 X 300 X 30 = 10800000

                       Since 10% of wall is mortar, then 10% of 10800000 = 1080000

                       Lets deduct the percentage of mortar from the wall ie. 10800000 - 1080000 = 9720000

                      

                       Now divide the volume of brick wall ( without mortar ) by volume of a single brick

                       9720000 / 2000 = 4860

                       So, we need 4860 bricks in total to build the wall of the given dimensions.

 

Q2. From a point O, two persons A and B started their journey on XY plane. A went 7 km along north and stopped. B went 5 km west and then 5 km south and stopped. What is the shortest distance between A and B?

(A) 13 km                                                                                           (B) 7 km

(C) 12 km                                                                                           (D) 3 km

Ans. ( A )

EXPLANATION:

The image provided below is a pictorial representation of the information given to us in the question ( Image X )

To find the shortest distance, AB

Join AC & BC ( Image Y )

Since, OD = 5 km, BC = 5 km

Since, DB = 5 km, OC = 5 km

Now, AB2 = AC2 + BC2 ( Pythageros Theorem)

   ie. AB2 = 122  + 52

        AB2 = 144  + 25

        AB2 = 169

        AB = 13

Q5. Which one of the following consumes least amount of electricity?

(A) Tungsten bulb

(B) Fluorescent Tube

(C) Light Emitting Diodes ( LED )

(D) Compact Fluorescent Lamp ( CFL )

Q1. One late afternoon, you along with your family members were enjoying a boat ride along a river and viewed a spectacular sunset. You noticed that the boat was moving from south to north and all of you were facing north. Suddenly, your youngest brother shouted and told everybody to see the river bank on your right side. You saw a series of high-rise apartment building interspersed with trees. But, in the middle, there was a beatiful river ghat, a garden and a small white mosque adjacent to it. Lots of birds were flying around and sitting on its golden dome. In the concrete jungle, the small structure seemed to be a nice relief. Develop a coloured sketch (use dry colour) of what you experienced.

 

Q2. You are waiting in a railway platform for catching a local train. Some people are also waiting there with small and big luggage. Few people are sitting on wooden benches.
