The Quantitative
Ability section of CAT is divided into sub sections or topics such as
Arithmetic, Algebra, Geometry, Mensuration and Trigonometry. This article will
talk about the topic of arithmetic, its components and preparation method in
detail..
Arithmetic
compromises basic mathematics and includes topics like Averages, profit &
Loss, Ratio & Proportion, percentages, Time, Speed & Distance etc. As
it covers a lot of topics, so it becomes an important and scoring sector of
CAT.
The components
This section is the
basic part of Quantitative Ability section of CAT. This section comprises of
basic mathematics and includes topics like Averages, profit and Loss, Ratio and
Proportion, percentages, Time, Speed and Distance etc. The calculation of the
Arithmetic part is not only based on formulae but it can be identified with day
to day life as well.
Preparation for Arithmetic
Preparation for
Arithmetic can be done on the basis of day to day life. Since the topics like
profit and loss, percentage, time and distance etc. are prevalent in our daily
life, you can utilize them and do mental calculation to increase your speed in
calculation.
For eg.; When
you travel and fill up fuel for your bike or car for Rs 500, ask the
price/liters and calculate the liters that you expect to get for Rs 500. So you
can see people number plates and find out the average, median etc of that
number.
A very simple but
effective way to improve your speed with numbers is to observe the numbers that
appear in a year and make all possible combinations with the four numbers –
ratio of first two and the last two, total of the four digits, inverted ratio,
etc. another could be doing calculations using mobile numbers, pin codes, etc.
Implication of this idea in daily life makes one comfortable with numbers.
It is good to relate
various such daily incidents mathematically and solve. Do lot of variations in
your thoughts, create different type of questions and answer them on your own.
Apart from that, you
should also keep in mind the basic guidelines such as getting enough practice,
taking practice tests and maintaining speed along with accuracy. One thing that
should always be kept in mind while preparing for these sections is that along
with speed, accuracy is also important. So it should be made sure that you do
not lose track of accuracy while concentrating on speed.
