VISUAL REASONING

Directions: Find the missing character from among the given alternatives.

Ex:1

(a)625 (b)25 (c)125 (d)156

Sol: clearly

so missing number

Hence , the answer is (a).

Ex:2

(a)25 (b)37 (c)41 (d)47

Sol: Clearly in fig

In fig

In fig (B) , missing number .

Hence the answer is (c)


15/20

Ex:3

(a)115 (b)130 (c)135 (d)140

sol: Clearly the number inside the circle is equal to the sum of the product of

the upper three numbers and the product of the lower three numbers. Thus,

In fig (A)

In fig (B)In fig (c), missing answer =

Hence the answer is (b).

Ex:4

(a)5 (b)4 (c)3 (d)2

Sol: Clearly in the second column, 22+2-23=1

In the third column, 40+5-43=2

In the first column, missing number = 21+1-20=2

Hence, the answer is (d).

Ex:5


16/20

(a)11 (b)6 (c)3 (d)2

Sol: Clearly in the first column,

In the second column,

Let the missing number in the third column be .

Then ,

Hence the answer is (c).
