Comparison Of Fractions:
Fractions is an important area where most people have problems, and this is a portion which is very much necessary in Quatitative Ability and Data Interpretation area of most competitive exams, like CAT,XAT,SNAP,MAT etc.So Lets discuss a few methods of identifying the largest or smallest fractions from a given set of fractions.
CASE-1: When numerators are same & denominators are different,The fraction with the largest denominator is the smallest, and the fraction with smallest denominator is the largest.
CASE-2: Different Numerator & Same Denominator, the fraction with largest numerator is …

Some of you will be having difficulties when multiplication of 9 comes.So here are some tricks with “NINE”.
MULTIPLICATION of TWO NUMBERs between 90-100
The trick is very simple,but again i stress on practice because if you dont practice, the technique won’t come to you when it is required.And knowledge  is absolutely worthless if it didnt help in need.
STEP:1 Find the difference of each number with 100,their product will give the last two digits of the final ANSWER.
STEP:2 Now to get the first two digits of the ANSWER you can either subtract the difference …

Numbers & Multiplication
                   Experts say numbers are very vast.From a CAT, XAT, MAT, or from any competative exam point of view numbers is got prime importance.When we talk about numbers the very basic things that we need to know are 4 operations “addition,subtraction,division,multiplication“.Of these the last one is bit time consuming compared to first two.So lets think of steps to reduce time in multiplication .

Finding SQUARES with ease
 I have mentioned a few tips in the same topic before,but here are a few more tricks.First of all certain things you need …

I have posted some speed maths posts before,here are a few more tips and tricks.These are the things i forgot to mention in the other post,these few things are very simple and basic but they will help you gain some time in your quatitative sections.
1.Squares upto 25.
2.Cubes upto 12.
3.Powers of 2 upto 10.
4.Powers of 3 upto 6.
5.Multiplication tables upto 20.
6.Reciprocals of integers upto 12.
Making all these through will surely help you.All these should be in both ways like,when we see 529 in a question 23 should come to our mind …

SQUARES
1. Square of a number ending with 5
Let y5 be the number then
square is :- y*(y+1)25
Eg :-
35 * 35 = 1225
3*(3+1)25=1225
2. Square of a number near to a known square
This is real simple you just need to look around ,the formula is very familiar.
(n+1)^2 = n^2 +2*n +1
Eg:-
35^2 can be found easily,so 34^2 = 1225-2*34-1=1156

To find the digit in the unit place of a number given in powers???
Have a look at the pattern below,here the case is with “powers of 2″
2^1 = 2
2^2 =4
