Question 57: Logical Reasoning and Mental Ability
Consider the following figures :
Which one of the following figures would logically come in the 7th position indicated above by a question mark ?

AnswerUPSC’s answer is (d).
Two things change independently. The inner symbol alternates circle, square, circle, square, so position 7 needs a circle, which rules out (c). The arrow arrangement repeats every third figure (figure 4 carries figure 1's arrows), so figure 7 carries the same arrows as figures 1 and 4, here with a circle. Among the circle options, only (d) matches that arrangement.
Why each option is right or wrong
- (a) Wrong. It is a circle, but its arrows differ from those of figures 1 and 4.
- (b) Wrong. It is a circle, but its arrows differ from those of figures 1 and 4.
- (c) Wrong. It has a square; position 7 needs a circle.
- (d) Right. A circle with the arrow arrangement that repeats from figures 1 and 4.
