DOT SITUATION
The problems on dot situation involve the search of similar condi-
tions in the alternative figures as indicated in the problem figure.
The problem figure contains dots placed in the spaces enclosed (a) (b)
between the combinations of square, triangle, rectangle and circle.
Selecting one of these dots we observe the region in which this
dot is enclosed i.e. to which of the four figures (circle, square,
rectangle and triangle) is this region common. Then we look for
such a region in the four alternatives. Once we have found it we
repeat the procedure for other dots, if any. The alternative figure (c) (d)
which contains all such regions is the answer.

DIRECTIONS (EXAMPLES 1-5) : In each of the following Sol. (b) Figure (X) contains one dot in the region common to
the circle and the triangle, another dot in the region
examples, there is a diagram marked (X), with one or more dots common to all the three figures and the third dot in the

(a), (b), (c) and (d) only one of which is such as to make possible figures (a) and (d), the region common to the circle and
the placement of the dot. Select this alternative as the answer. the triangle lies within the square. In figure (c), there is
no region common to the circle and the triangle. Only
Example 1 : figure (b) contains all the three types of regions.

Example 2 :
Sol. (a) In figure (X), one of the dots is placed in the region
common to the circle and the triangle and the other dot
is placed in the region common to the triangle and the
square. From amongst the figures (a), (b), (c) and (d),
only figure (a) has both the regions, one common to
(X) circle and triangle and the other common to triangle
and square.

Example 4 : the circle and the triangle. Figure (a) does contain a
region which lies in the square alone. Figures (b) and
(d) do not contain any region common to the circle and
the triangle. Only figure (c) contains all the three types
of regions.

(X) SIMILARITY IN FIGURE

In such questions a problem figure is given and there is a set of
four answer figures marked as (a), (b), (c) and (d). One of the
answer figure is exactly similar or identical figure to the problem
(a) (b) figure given. The candidate is required to identify the figure from
amongst the figure, which is exactly similar to the problem figure.
For example, consider a problem figure.

Sol. (c) In figure (X), the dot lies in the region common to the
circle and the triangle only. Such a region is present in Answer Figures

Example 5 :

(X) Figure (c) is identical to problem figure, for solving such problems
following point must be kept in mind.
(a) (b) 1. Carefully observe the problem figure and its design or pattern.
2. Compare this problem figure with answer figures one by one.
3. Always consider the black dots, small lines, shaded portion
and any number given in the figure minutely.
4. In some cases mirror images or water images are given in the
(c) (d) figure, so try to correlate and identify the relationship, then
you can choose the correct answer from problem figure
rapidly.
Sol. (c) Figure (X), contains one dot in the square only, an-
other dot in the region common to the square and the 5. If figure contains some arrows , then directions of arrows
