# SBI PO Data Interpretation Model Practice Problems with Solutions - Bar Charts

Friends, in our last post we have discussed about the introduction and preparation tips of Data Analysis and Interpretation section of SBI PO Exam. Read that post here before going to read below mentioned post. Now lets have a look at our preparation plan.

• Day 1 : Introduction (over)
• Day 2 - 7 : Introductory Practice problems on various types of Data Interpretation models
• Remaining Days upto the exam date : Practice problems of various difficulty levels with shortcuts.
Friends, in this post we shall work with an example problem of Barchart.

Directions (1-5). Study the following graph carefully to answer the questions that follow :
Production and sale of printers of various companies in a month
• Y axis represents the number of units produced
• X axis represents the number of units sold

Note : As this is our first problem, to make things easier to understand, we gave you the tabular format of the data along with the bar diagram (marked in red circle). But in exams they wont give you the data in this much detail.

1. What is the respective ratio of the total production of companies 4 and 5 to the total sale of the same companies ?
Solution :
Total Production of companies 4 and 5 = 850+550 = 1400
Total sale of companies 4 and 5 = 450+200 = 650
So, required ratio = 1400 : 650 = 28 : 13

2. What is the average number of units produced by all the companies together ?
Solution :
Required average = (900+700+300+850+550+600) / 6
= 3900/ = 650

3. Which of the first three companies had the highest percentage of sale with respect to its production ?
Solution :
So,
Percentage of sale :
1st Company = (650/900) x 100 = 72.2%
2nd Company = (300/700) x 100 = 43%
3rd Company = (150/300) x 100 = 50 %
So the answer is 1st Company

Note : It is obvious from the graph. So there is no need of calculation, in exam you can directly pick the answer from the given options.

4. What is the average number of units sold by all the companies together ?
Solution :
Required average = (650+300+150+450+200+400) / 6
= 358.33

5. The total units sold by these companies 1, 2 and 3 together is approximately  what percent of the total units produced of these companies ?
Solution :
Total units sold by the companies 1, 2 and 3 =  650+300+150 = 1100
Total units produced by companies 1, 2 and 3 = 900+700+300 = 1900

So, Required percentage

= (1100/1900) x 100 = 58

That's all for now friends. In our next post we shall work with the example of Pie Chart. Happy Reading :)
