Here is the shortcut trick for **HOW TO QUICKLY FIND AVERAGE OF NUMBERS**

It is not that difficult to find the average of numbers.

For
most of the candidates who are preparing for competitive exams like SSC, IBPS
etc. it can take some time to solve average questions asked in the SSC exams. But
what if we know a shortcut method to find the average of numbers, it will not
only let us solve the questions quickly but also save our time in the exam and
time is precious in competitive exams. So to help you, here we are sharing with
you some of the good shortcut tricks to find the average of numbers quickly.

The basic method of finding **average of numbers** quickly is

Average of numbers= sum of numbers/total No. of numbers

Or you can use the below formula

Suppose you are given a question as given below:

Find the average of 5,7,9,11,13?

Sol. Whenever you are given a question like the one above:

Here is a very simple trick for this type of questions.

In this type of questions, first look for the difference of
numbers. Since the difference is constant throughout i.e. 2. And given numbers
are odd in numbers i.e. total 5 types of numbers.

Then in this type of questions, the answer is always the
middle term i.e. 9 (in above question).

But if the numbers were given even in numbers means there
are six numbers like 5, 7, 9 , 11, 13,15. Then the answer is always sum of
middle terms or sum of opposite terms divided by 2 i.e. (5+15)/2 or (7+13)/2 or
(9+11)/2. The answer is always same. In the above case the average will be 10.

Suppose you are given a question like the one given below:

A batsman in his 10th innings makes a score of 75 and
thereby increases his average by 5. What is his average after 10 innings?

Here is the solution:

Let his
average after 10th innings be x, then

Total score after 10th innings= 9x + 75 = 10 (x + 5)

So x = 75 – 50 = 25

So his average after 10 innings = x + 5
