Question

The shape of a gilli, in a gilli-danda game, is a combination of

(a) two cylinders
(b) a cone and a cylinder
(c) two cones and a cylinder
(d) two cylinders and a cone

Answer 1

Hint: In order to solve this problem, we need to divide the problem into three parts, that is the middle section of the left section and the right section. Also, we need to understand the term cylinder and cone. A cylinder consists of two circles with surfaces parallel to each and the space between them is wrapped by the curved surface. Cone can be explained as the centre of the circle stretched out of the plane of the paper resulting in the cone.

Complete step-by-step answer:
We have been given a figure and we need to identify the shapes that the figure consists of.

As we can see that it’s not a 2-D but a 3-D figure projected on a 2-D surface. Let's start by identifying the middle section.
The middle section can be shown as follows.

The above figure is a cylinder.
A cylinder consists of two circles with surfaces parallel to each and the space between them is wrapped by the curved surface.
It can also be explained as the circle drawn on a paper and the circle is extruded on the plane perpendicular to the surface making it a cylinder.
Hence, the gilli-danda has one cylinder in it
Let's move on to the second object which is to the left of the cylinder.
It can be shown as follows,

We are talking about the figure that is not drawn by dotted lines.
The surface we are talking about is a cone.
A cone has a circular base and a pointed tip.
Cone can be explained as the centre of the circle stretched out of the plane of the paper resulting in the cone.
The base of the circular cone matches with the circular side of the cylinder.
Therefore, gilli-danda has a cone.
Let’s move on to the shape to the right of the cylinder

The above figure is the exact mirror image of the previous image.
Hence, the figure is also a cone.
The base of the second cone matches with the circular side of another cylinder.
Hence, gilli-danda has 2 cones.
Therefore, in all, there are 2 cones and a cylinder in gilli-danda.
So, the correct answer is “Option C”.

Note: We need to imagine that these are not 2-D figures but 3-D images. After the first step, we can say that there is only one cylinder in the figure. So the option (a) and (d) can be eliminated. We can also eliminate the option by saying that as the figure is symmetric so there cannot be just a single cone on the figure. This eliminates the option (b) and (a) and (d).
