Problems on dot fixing situation test involve the search of exact similar situations in the answer figures as indicated in the problem figure (X). The fig. (X) contains a single dot or more than one dot placed in the spaces enclosed between the combinations of a squares , a triangle , a rectangle and a circle. Selecting one of these dots we observe the region in which this dot is enclosed . We now find such a region in the four answer figures. On finding this dot, the procedure is repeated to find the other dots if any. The answer figure which contains all such dots in the regions is the answer.
