What are the Quick Tricks for Quantitative Aptitude

Quantitative Aptitude Tests evaluate numerical ability and problem solving skills of candidates. This test forms the major part of a number of important entrance exams for different fields.

In this section, we are going to discuss the one of the most important topic – “Percentage”. Let us discuss these tricks to efficiently handle “Percentage” topic.

Trick 1

To begin with, let us solve this basic question. You need to find as to which one is the higher of the following two –

a)    3% of 234

b)    234% of 3

Most of the students would say that the answer is 234% of 3. Before we give you an answer, let us understand the basics of “Percentage”

We write “%” as (1/100) and the meaning of “of” is ‘Product’ of the given values.  Now,

  1. 3% of 234 = (3/100) X 234
  2. 234% of 3 = (234 /100) X 3

If you observe this carefully, you will come to understand that both of the above values are equal. This leads to a very important understanding – order does not matter if the values that are in the consideration are equal.

a % of b = b % of a


Trick 2

To begin with, let us solve the following problem –

Population of a village increases by 10% every year for two years in a row. By what percent, the population will increase effectively after two years?
Population at the end of the first year – 100 + 10% of 100 = 110Let us say that the population of the village is 100.

Population at the end of the second year – 110 + 10% of 110 = 121

Hence, the growth of the population in two years = ( ) x 100

=  x 100 = 21 %

Hence the population increases effectively by 21 % after two years.

Now, let us introduce ‘ab’ formula. You should use it when the given value undergoes two successive changes.

Final % change after two successive percent changes  ‘a’ and ‘b’ –      a %+b% +  %
Here in the given problem –                      a = 10%, b = 10%

Now, let us use this formula to solve the above mentioned problem

= 10 + 10 + ()

= 21% (Could you see that we have solved the problem in a single line. Is it not amazing)?

Now, you solve the problems given below by using these techniques and put your answers in the ‘comment tab’.
