Dear Participants, Data Interpretation Framework Types of Variables: 1. Discrete: Take values in steps for example years, companies, regions 2. Continuous: They change continuously for example sales revenue, GDP etc. Most of the time in all kinds of data problems we see interplay between a discrete & a continuous variable. For instance year vs sales etc. Charts between two continuous variables are rarely seen. Methods of Representing Data: 1. Tabular: Master Data Set 2. Bar Charts: For Depicting Trends 3. X-Y Charts (Line charts):For Depicting Trends 4. Pie Charts: For depiciting proportions of each 5. Caselet Forms: Data in Raw Form So all our questions revolve around these five data types & the interplay of discrete & random variables. Type of Questions: i. What percentage of x is y. ii. What proportions is x of y. iii. Growth Rate: Year wise or over multiple years. iv. Average cost/price/revenue. v. X & Y are they directly proportional/ inversely proportional. These Questions & there handful of other variants are based on your Quant 101 topics viz. Percentages, Ratios & Averages. To master DI section thus you have to be: Step 1: Be good at calculating percentages & ratios (Which I guess you must be good at). A few Vedic Mathematic tricks can also be learnt to speed up that part. Step 2: Be mindful of the data presented. The data would generally be nested, one table leading to another line chart/bar graph or pie chart. So you need to remember each chart’s function. And locate the data accordingly to solve. Finer points to remember in DI: i. There is not much variety in the questions, it is just the numbers & the names are changed. So if you are comfortable with each type of data depiction & how the different types of data charts are linked. ii. Do not unnecessarily solve percentages or ratios you don’t require. iii. Just see the data broadly to get a sense of it & proceed directly to questions. iv. Sometimes the last or last 2 questions are highly calculation intensive. This is purposefully fully done to waste your time by the question setter. In that case safely leave that question of the data set & move on. v. Keep few percentages & ratios at hand: Here is an indicative list: 1/2=50% ; 1/3=33.33% ; ¼=25% ; 1/5 = 20% ; 1/6 = 16.67% ; 1/7= 14.28% ; 1/9 = 11.11% ; 1/11 = 9.09% ; 1/13 = 7.69% ; 1/14 = 7.14 % ; Now the numerator in all these ratio is 1. If you remember these basic percentages then for getting say 2/5 just multiply 1/5 = 20%*2 = 40% ; So anything different in numerator can be quickly multiplied with.

Sir i have given around 40 mocks but i think i will be able to revise 20 or so....how should i revise all 40 in this week?

02:36 PM

ANY last min lr tips

02:41 PM

@Shreya your first priority would be to revise the mocks in which you have scored less, this would help you understand where you went wrong an how to avoid that in the exams. Revising 20 mocks I think would be more than enough. What you should also concentrate is on revising the basic formulas. I want you reaction time to questions to be minimum across all sections & this would be achieved if you are fresh with those formulas & tricks. So 20 mocks is ok provided yo revise all the important concepts.

02:41 PM

thanks so much :)

02:43 PM

Hi Aman, Would you suggest attempting any mock in these last days

02:43 PM

@all Prajwal for LR it is important to have strong familiarity with different questions. So solve max 1-2 questions across all types. Should take not more than 8-10 hours then you are good to go.

@eshwar that depends on how many mocks you have given. If a sufficient number (15-20) have been given, then its of no use. Revising the concepts should be your top priority. If not given then I strongly suggest appearing in mocks to understand the flavou of the paper.

02:51 PM

Hi Aman, I have improved a lot on set selection before starting to solve, but i an not able to solve more than 3-4 sets (only after picking). I always run out of time. How to get faster and solve more sets...?

02:52 PM

@Shobhit there are two parts to it: 1. Understanding the question 2. Speed of calculations Which one are you lacking in DI ?

02:53 PM

Mosty after starting the set.. it gets tougher from ques no- 2 onwards and it keeps taking more n more time in solving them.

02:56 PM

I don't have a good grip for Di and lr...and also in the mocks I have performed very badly. So please guide me with a strategy for the next 6 days left for the test

@all one thing that you strongly need to be aware while solving DI sets is linkages between Data Charts..The Table format of data is the master set which is more visually depicted through line & bar charts (for trend analysis) and Pie Chart (for composition analysis). Thus merely seeing the type of chart would give you firsthand what kind of questions would be therein

02:57 PM

Thank you Aman. I have got your mail

03:00 PM

One more question... When solving DI/LR, There is a situation in the last 8-10 mins that u r stuck at an LR and eventually couldnt solve/mark it.. how to avoid this situation of wasted time, should we never attempt LR towards the end?

03:01 PM

@shobhit More often than not the follow on questions after the first one are more calculation intensive version of the first one and test your linkages between data sets. For this you should two things: i. Speed up your calculations, use few Vedic Math techniques (multiplying, division, squares & cubes would do); Need not go in depth at this stage of preparation. ii. Once more revise your basic DI structure. The entire crux of DI lies in knowing which chart does what. If that is clear in your mind, you can quickly guess the question setters intent.

03:05 PM

Aman, I have observed a visible difference in DI and LR sets by various providers Usually TIME and CL sets are lengthy and to an extent solvable 2IIM sets look easy on the surface level but the questions are really tricky Would you suggest to just concentrate on previous papers mocks or just solve any random DI set taken from previous mocks

03:05 PM

how was last year's dilr??

03:09 PM

@trishula there is no need to worry. There is still decent amount of time to grasp the concepts. Step 1: Pick any basic LR&DI book or either any coaching's material. I used CL & Arun Sharma. Then revise the basic theory behind all the data charts & attempt 10-15 questions from each topic. This entire exercise shall take about 2 days. Step 2: On the third day attempt full length sectional test for LR&DI. With a good grasp of topics, I am sure you would feel more comfortable with LR&DI on the third day. After the third day, concentrate on QA & VA. But this strategy would work only if you completely devote yourself for the next three days. All the best :)

Thanks Aman for answering my query..:-)

03:19 PM

@shobhit I have personally been inn such situations across many mocks & was frustrated to see my last 10-15 minutes go waste. So what I used to do was first attempt the non-case based questions for first 10 minutes or so. It builds up confidence. Then i used to skim through the LR sets and figure out which ones I am familiar with. The familiar ones were solved quickly to ram up pace. The non-familiar ones were left for the end. Remember our goal is to maximize our score and nothing other than that. LR's are like a puzzle, if you know you know, if you don't then you might do it but there is high potential of spending disproportionate time on them. Hence that must be avoided at all cost, even if that means solving all of them at the end. Only solve the familiar ones at the outset.

03:20 PM

Thanks Aman.. Got it. Will keep that in mind.

03:24 PM

@eshwar i gave mocks across all three CL, Time & IMS. I am telling from experience that the CAT paper is not much different from them. The level & the type would be the same. Gone is the pre 2009 era when CAT used to be literally the Da Vinci's code. Its just about familiarity & speed. So since you have already given close to 40 mocks, in my opinion you just concentrate on revising the basics & the key issues that you found in the past questions you attempted, rather than trying something new. That should be more than sufficient :) All the best !!

03:25 PM

@bosco last year's LR&DI was moderate to tough. I expect the trend to be similar. Hence in such situations question selection also forms a key part of performance.

03:31 PM

Thank you Aman. Can feel the positive vibe in your answers every time. It's very encouraging for the aspiring students. All the best with your Intern at Furlenco, if I'm not wrong. Guess you got placed already by now being a topper of your batch :)

03:32 PM

@all It was my pleasuring interacting with you all. Will soon send you the DI Framework doc. Feel free to mail me back. Tomorrow's session would be on LR. All the best. Cheers Aman

03:32 PM

@eshwar I am sure you will ace the CAT & beyond as well. All the best. Regarding any personal stuff do feel free to mail.
