Reasoning is another section in CLAT that doesn’t require any prior subject knowledge or mugging up formulae. Students from all streams are on the same page with this section. So it gives a scoring opportunity to everyone. To make matters slightly complicated, CLAT Logical Reasoning (LR) section is a mix of Maths and English.
Similar to the GK section, LR requires smart preparation. Identifying high weightage topics and practising them first, followed by the rest, is the key. From CLAT 2013, the LR section changed a little, but in terms of topic wise importance as follows:
Family Tree/Relationship – 5
Series completion – 5
Circular/Matrix arrangements – 5-8 (1-2 caselets)
Directions, puzzles etc – 2-3
Analogies – 5
Statement – Inference – 3-5
Strong-Weak arguments – 3-5
Syllogisms – 5
Parajumbles/Para completion – 3-4
CLAT 2015 was an aberration, where 12-13 questions each were asked on case-based reasoning and coding-arrangement type of questions. Otherwise, English and Maths are equally important.
Lets look at a few Mathematical Reasoning questions and a general approach to solve them.
Matrix Arrangements (CLAT 14 caselet)
Five friends — Satish. Rajesh, Rehman. Rakesh. and Vineet — each presents one paper to their class on Physics, Zoology, Botany, English, or Geology one day a week, Monday through Friday.
(i) Vineet does not present English and does not give his presentation on Tuesday.
(ii) Rajesh makes the Geology presentation, and does not do it on Monday or Friday.
(iii) The Physics presentation is made on Thursday.
(iv) Rehman makes his presentation, which is not on English, on Wednesday.
(v) The Botany presentation is on Friday, and not by Rakesh.
(vi) Satish makes his presentation on Monday.
1. What day is the English presentation made?
2. What presentation does Vineet do?
3. What day does Rakesh make his presentation on?
The ‘Grid’ Approach –
If the available information is properly entered in the grid, the caselet generally solves itself. Based on the information given in the caselet, one can populate grid as follows –
With practice, a typical matrix arrangement should not take more than 5 to 7 minutes to complete. Since average time per questions tends to be higher in LR, dedicate lesser time to GK and partly verbal section.
Family Tree/Relationships (CLAT 2014 question)
Pramod told Vinod, “Yesterday I defeated the only brother of the daughter of my grandmother”. Whom did Promod defeat?
Directions (CLAT 14 question)
Two buses start from the opposite points of a main road 150 km apart. The first bus runs for 25 km and takes a right turn and then runs for 15 km. It then turns left and runs for another 25 km and takes the direction back to reach the main road. In the meantime, due to a minor breakdown, the other bus has run only 35 km along the main road. What would be the distance between the two buses at this point?
(A) 65 km
(B) 75 km
(C) 30 km
(D) 85 km
Series completion (CLAT 14 question)
1. 0, 6, 24, 60, 120, 210, ___?
Each term is a multiple of three consecutive natural numbers
e.g. 0=0*1*2, 6=1*2*3, 24=2*3*4, 60=3*4*5, 120=4*5*6, 210=5*6*7. Hence next term should be 6*7*8=336
2. POQ, SRT, VUW, ___ ?
Pls note the jumbling of consecutive characters in alphabet series
While these are standard approaches to solving LR questions, you should be prepared to handle surprise elements like calendars and data sufficiency, that were introduced in CLAT 2015. Solving LR caselets in small groups may help in terms of covering more caselets in shorter time. Making teams of 2 each and solving puzzles can help in improving speed.
We shall cover the approach for verbal reasoning in another post. Meanwhile, start thinking LAWgically!
