Verbal and Non - verbal Reasoning
Category : 10th Class
In this chapter, we will solve problems related to reasoning and aptitudes as we know that Reasoning and logic skills are an integral part of Mathematics.
Find the Missing Number
In such types of problems, we have to choose a missing
Number (or character) in the figure out of given options.
Example:
Find the missing number in the following figure.
(a) 1728 (b) 1331
(c) 729 (d) 512
(e) None of these
Answer (b)
Explanation: Here the pattern is ________
\[{{(18+10+8)}^{{}^{3}/{}_{2}}}=216\],
\[{{(15+12+22)}^{{}^{3}/{}_{2}}}=343\],
\[{{(57+43+21)}^{{}^{3}/{}_{2}}}=1331\]
Direction Sense Problems
In such types of problems, we draw a diagram by using the given information. The following diagram shows all the Direction in a proper manner.
Example:
If P is to the north of Q and R is to the west of Q, then in which direction is P with respect to R?
(a) North-east (b) South-west
(c) North (d) South
(e) None of these
Answer (a)
Explanation: Clearly from the diagram it is clear that P is
In north –east direction with respect to R.

Example:
Find the figure which comes next in the series.
(a) (b)
(c) (d)
(e) None of these
Answer (b)
Explanation: Each next figure rotates \[45{}^\circ \] anticlockwise in each block and one line is added to its top and Bottom alternatively.
