# Bar Diagrams

The Bar Diagram is the basic model of the Data Interpretation Problems. The bar diagram is a two dimensional graphic representation where the elementary graphic objects are a set of rectangles or bars drawn in parallel so that the extension of the same is proportional to the magnitude they intend to represent.

Here the rectangles, or bars, can be either horizontally or vertically positioned.

If only one bar is given in the graph, then  that diagram is called a simple bar diagram.

Have a look at the Following bar diagram. It  gives us the information of the production of a company in various years.

Now lets have a look at a problem based on this Simple Bar diagram.

What is the average production of the company over the years ? (followed by some options)

Now just find out the average of the production.

So here, 333 is the answer. ( Remember, here you should add all the terms mentally and put that 2000 on paper and then divided that with 6.

1. give some exercise for this .

2. I need some more examples along with anyyyyyyyy shortcuts ? ? ?

3. THANK YOU SO MUCH. THIS SITE IS VERY USEFUL FOR ALL BANK EXAM WRITERS.GOOD JOB. ONCE AGAIN THANK YOU

4. very useful site 4 bank exam

5. How do I assume the2004 value is 250 and not 260 facing this bug in many problems mostly in places where the bar is just above or below the centre

1. In these sort of problems... Especially DI.. We take approximate values.. Even if u take it as 255 or 260.. The difference between the avg maybe negligible.. to follow the time Management.. Appropriate values are not required..

6. How do we ascertain the value of 2004 is 250 and not 255 facing this problem in many more questions

7. Thanks...coulld you plz post more example...

8. 9. so good question
