JEE Mains Paper 2 Sample Paper

Anu Handa


We’ll discuss some questions from JEE Mains Paper 2 for B.Arch, Aptitude Test


The first question here tells us to....

1.  Identify the correct 3D figure from the answer figures, which has the elevation as given in the problem figure on left

To answer such questions, we should always remember,

a. 3D figures have 3 Dimensions – Length X Breadth X Height

b. A top view has 2 Dimensions – Length X Breadth

c. And an elevation also has 2 Dimensions – Height X Length / Breadth


So coming to the first question now, we can see an elevation on the left & four 3D figures on the right, out of which we have to choose one that has the elevation given on the left. 

Now, I must tell you that once you understand, how to solve such questions, they become super easy & take minimal time.


For Example, by just glancing over the question, I can figure out that the 3rd option is the correct answer.

I will tell you later, how I was able to identify the answer.


But first the easier, way out.......

In the above figure you can see the arrow denotes the position of the viewer, which is exactly perpendicular to the 3D figure.


We assume that we have a transparent sheet placed in between the arrow and the 3D figure.

To draw the correct elevation, we draw projections, as shown in blue, from the 3D figure to the transparent sheet.


The highlighted portion in red is the correct elevation.

The highlighted portion in red above is further filled in with purple, so now, we know for sure that the correct option is OPTION 3.


After, you have done such exercises a number of times, you will be able to solve the questions without even drawing the projections.


We’ll see how it works…

We’ll adopt the process of elimination here…

We know in the problem figure (elevation) above, we can see 2 shapes, the bottom one is a rectangle & the top one is a triangle.

So, we can directly eliminate the 1st option because if we take the projections of this 3D figure, we will just get the triangle & not the rectangle.


Also, we can see in the elevation above, there is a gap between the edges of these 2 shapes, which we’ll not be able to see if we take the projections in the 2nd & 4rth figure, so definitely we can eliminate these 2 also.

This leaves us with the 3rd answer, here as we can see that when we take projections, it matches the elevation on the left.


If you are not able to follow this method, it’s definitely ok, as the understanding comes after a lot of practice. 

You can draw the projections & find out the correct option.

The 2nd question says

2. 3D problem figure shows the view of an object. Identify the correct elevation as indicated by arrow


In the above question, if we follow the process of elimination, we can easily come to the conclusion, that the correct answer is OPTION 3


Lets see how.......

When we stand perpendicular to this 3D figure, we can see this triangular shape (Marked in Red) in elevation, which is not there in option 1st, 2nd & 4rth.

We can see it’s only present in option 3



Also, when we take projections, we can see that option 3 is the correct answer.




Aptitude Questions as shown above are easy to score & require minimum time to solve.

But to gain a good level of expertise, you need to practice well.


Good Luck!!
