## QUANTITATIVE ABILITY & DATA INTERPRETATION

### QUANTITATIVE ABILITY & DATA INTERPRETATION

The trend of this section in XAT has been characterized with hardly component of Higher Maths in the past 2 years. The questions have been designed in such a way that they test basic conceptual knowledge along with logical reasoning /understanding skills of the student. This has probably done so as to encourage students with a varied profile (especially non – engineers) to appear for the exam and also attempt a greater no. of questions.

In comparison to last year, the Quant Section was comparable to last year’s paper in terms of level of difficulty with Maths questions being marginally easier but the Data Interpretation being much tougher requiring higher reasoning and calculation skills. Also the number of topics covered was much wider in this year’s paper.

The breakup of the section is as follows:

The arithmetic area was probably easier than the other areas. The questions on Time & Distance and Time & Work were easily doable. Questions on Statistics as well as some questions on Numbers and Geometry were very much solvable for a student whose quant fundamentals are strong.

Questions on Data Interpretation were also in this section. Though the DI part appeared lengthy, it was solvable with a bit of concentration. For instance, the Data Interpretation set on the Football teams could have been done away with. The table on Indian Economy (GDP, current account etc) though slightly cumbersome in calculations was a sure shot as using approximation one could have easily arrived at answers for 2 of the 3 questions. Also for the 3rd question (determining the true statement) it became pretty obvious that the first 2 statements were not necessarily true and then looking at the options with no “None of the above” option, one could have marked option C.

The other DI set that one should have attempted and solved is the one on Country of Ten, which though long in reading was quite easy to analyze. Other must do questions were the ones on Prof. Mandal, circular pool of city’s Municipal Park, Mr Mehra, Albela Bob & Chulbul, points on the square, maximum value with pq, whole numbers between 100 & 800, Interesting number, probability a/b, Country of Four. For the students who are reasonably good in Quantitative Aptitude question with finding minimum value with abc, Sara’s friends, indices with p & q, Ram Shyam & Hari, base number system (xxx) and remainder of polynomial function, Taxi to Wasseypur, Graph on Functions were the other score maximizers.
