Quick DI inputs..

While searchin some good contents for DI to start with i came across some really good contents on DI. Althought these are very easy question, but this would act as a starting point for all of those who are still struggling to start with DI from the scratch...

Here we go...

Unraveling the Purpose of Data Interpretation
Data Interpretation section virtually puts a student in the shoes of a Business Manager, who is inundated with useful (and not so infrequently with useless) data and has to make some quick interpretation of the data to reach important decisions. Once presented with graphs or tables, the mental processor of a manager starts whirring at the top gear and selects, prunes, manipulates, and compares the data and reaches certain conclusions. Successful operations of these processes require that a manager possesses qualities like:

o An eye for detail,

o An ability to focus on key issues quickly,

o An ability to work on numbers in different ways,

o An ability to see a trend,

o An ability to identify exceptional situations,

o An ability to work with logical relationships and An ability to reach a conclusion using deductive logic.

Well, here i am putting some D Iquestion for you to solve them from one of the DI doc i have with me. These examples are fro mCAT 2001 and are really simple..Give yourself a quick shot and test where you stand...

Question 1 to 3

There are six companies, 1 through 6. All of these companies use six operations, A through F. The following graph shows the distribution of efforts put in by each company in these operations

Q1. Suppose effort allocation is interchanged between operations B and C, then C and D, and then D and E and if companies are then ranked in ascending order of effort in E, what will be the rank of company 3?

Q2. A new technology is introduced in company 4 such that the total effort for operations B through F gets evenly distributed among these. What is the change in the percentage of effort in operation E?
1. Reduction of 12.3 2. Increase of 12.3
3. Reduction of 5.6 4. Increase of 5.6

Q3. Suppose the companies find that they can remove operations B, C and D and re-distribute the effort released equally among the remaining operations. Then, which operation will show the maximum effort across all companies and all operations?
1. Operation E in company 1 2. Operation E in company 4
3. Operation F in company 5 4. Operation E in company 5

Question 4 and 5

I am also planning to update this blog with some more inputs on QA topics like Logarithms, Progression.

Also on 18th we have a national MOCK CAT..All the best to all fellow aspirants..
