Series last figure and middle figure missing: These problems revolved around geometrical figures and can be solved by simple counting or multiplication. There might be multiple figures apart from simple geometrical figures to confuse the test taker. These questions rarely involve complex logic but are time consuming and students tend to feel exhausted after concentrating for a series of such questions.

1.4 Please identify the figure which comes next?

This is a simple question and in quick glance the student will realize there is an addition of "1" line in geometrical figure --- Triangle --- Square --- Pentagon ---- Hexagon---?

Logically the next figure to follow is Heptagon also referred as Septagon by some

1.5 Please find the missing figure?

A variation of the above (series completion) question is the missing figure within the series rather than at the end of the series. Such questions require a complete reading of the question rather than a quick scanning. Students are prone to commit minor errors while reading the questions and derive a faulty logic. Students are advised to read such questions twice if required but to ensure they derive the correct logic. In the above question the same logic is followed --- --- Triangle --- Square ---? ---- Hexagon--- Heptagon

Similar Pair: These are the most time consuming and logic oriented questions in MHCET 2012. There is one master pair which will have some deviance in activity from one block to another (clock wise movement, anti clock movement among others). The following example will give a better understanding of such questions:

1.6 Please find a pair similar to:

In the above "master pair" we observe that the arrow moves by 90 degree anti clock wise. This movement of 90 degree anti clock wise has to be replicated in the correct option. In option 1 there is a 180 degree movement hence it can be ruled out. In option 2 while there is 90 degree movement it is clockwise which does not confirm with the logic. In option 3, the frames are mirror images of each other. While in option 5 there is again clockwise movement. Option 4 confirms with the logic of 90 degree anti clock wise movement and is the correct answer.

Dissimilar Pair: These questions are an add-on to the similar pair questions. In these questions derivation of logic of the master pair is imperative. Once has to carefully navigate the answer options to ensure he/she chooses a "dissimilar pair". Many students in haste mark the first similar pair they find, which is exactly opposite to the answer required. I will again stress the importance of reading question and answer options very minutely for such questions.

1.7 Find the pair dissimilar to the below pair?

As we can observer there is 90 degree anti clock wise movement in the master pair. Hence any pair which does not have 90 degree anti clock wise movement will be the appropriate option. Let's take a pictorial understanding of the answer options:

As we see apart from option 3 all the options confirm with the 90 degree movement. Hence option 3 is the dissimilar pair and the correct answer.

A variation to this can be a dissimilar pair without master. Hence logic cannot be derived by just looking at one diagram. These questions consume a lot of time hence should be attempted only if the candidate is confident of his/her visual reasoning solving skills. Candidates must ensure that they build logic after viewing all 5 options, while they are building the logic, the dissimilar pair will be noticed simultaneously. For example let's take the above question without the master pair:

1.8 Find the dissimilar pair among the following?

If we observe the options 1 and 2 we notice there is a 90 degree anti clock wise movement in the colored area. The same 90 degree shift is observed in option 4 and option 5 as well. Only option 3 does not confirm with the logic and hence is the dissimilar pair. In the MHCET exam expect questions trickier and more time consuming than above.

In the third part of the series we will concentrate on logic derivation methods in visual reasoning.
