Comprehension:
Direction: Study the following graphs and answer the following questions.
The graph shows number of phones sold by three different companies in four different months.
What is the difference b/w the total number of phones sold by Nokia and Oppo in June to the number of phones sold by Vivo and Oppo in July?
Answer (Detailed Solution Below)
Line Graph Question 2 Detailed Solution
Given:
Number of phones sold by Nokia in June = 350
Number of phones sold by Oppo in June = 500
Number of phones sold by Vivo in July = 350
Number of phones sold by Oppo in July = 250
Calculation:
Total number of phones sold by Nokia and Oppo in June = (350 + 500) = 850
Total number of phones sold by Vivo and Oppo in July = (350 + 250) = 600
∴ required difference = (850 ─ 600) = 250
Line Graph Question 3:
Comprehension:
Direction: Study the following graphs and answer the following questions.
The graph shows number of phones sold by three different companies in four different months.
What is the average number of phones sold by Oppo during the given months?

Top Line Graph MCQ Objective Questions
The line chart given below shows the profit percentage of a company on 5 different products P1, P2, P3, P4 and P5.
The expenditure of product P5 is Rs. 46000. What is the revenue of product P5?
Answer (Detailed Solution Below)
Line Graph Question 6 Detailed Solution
Download Solution PDFGIVEN:
From the chart
Profit percentage in P5 = 8%
Expenditure = Rs. 46000
FORMULA USED:
Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100
CALCULATION:
Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100
⇒ 8 = [(Revenue – 46000)/46000] × 100
⇒ Revenue – 46000 = 8 × 460
⇒ Revenue = 3680 + 46000
⇒ Revenue = 49680
Study the line graph and answer the question that follows.
The line graph represents the number of vehicles (in thousands) manufactured by two automobile companies A and B over the years from 2010 to 2015. The X-axis represents the years and the Y-axis represents number of vehicles in thousands.
(The data shown here is only for mathematical exercise. They do not represent the actual figures of the country.)
The average value of the vehicles manufactured by Company A is what per cent of the average value of the vehicles manufactured by Company B during 2010 to 2015?
Answer (Detailed Solution Below)
Line Graph Question 7 Detailed Solution
Download Solution PDFCalculation:
Total value of vehicles manufactured by company A during 2010 - 2015 = 260 + 218 + 224 + 179 + 266 + 348 = 1495
Average value of vehicles manufactured by company A during 2010 - 2015 = 1495/6 = 249.16 (in thousands)
Total value of vehicles manufactured by company B during 2010 - 2015 = 307 + 270 + 250 + 289 + 310 + 416 = 1842
Average value of vehicles manufactured by company B during 2010 - 2015 = 1842/6 = 307 (in thousands)
∴ Required percentage = 249.16/307 × 100 = 81.2%
The line chart given below shows the profit percentage of a company on 5 different products P1, P2, P3, P4 and P5.
The revenue of product P3 is Rs. 38100. What is expenditure of product P3?
Answer (Detailed Solution Below)
Line Graph Question 8 Detailed Solution
Download Solution PDFGiven:
The revenue of product P3 is Rs. 38100.
Formula used:
Profit% = (revenue – expenditure)/expenditure × 100
Calculation:
The revenue of product P3 is 38100,
Let expenditure be Rs. y.
⇒ Profit% = (revenue – expenditure)/expenditure × 100
⇒ 27 = (38100 – y)/y × 100
⇒ 27y = 3810000 – 100y
⇒ 127y = 3810000
⇒ y = 30000
∴ Expenditure of product P3 is Rs. 30000
The line chart given below shows the ratio of imports to exports for a country for 5 consecutive years. Y1, Y2, Y3, Y4 and Y5.

Answer (Detailed Solution Below)
Line Graph Question 9 Detailed Solution
Download Solution PDFThe ratio of import and export for Y3 is 1.1

∴ Imports for year Y3 = 35000 × 1.1 = Rs. 38500 crore
A company has five plants for manufacturing spare parts. Each plant manufactures local quality and export quality.
What is the ratio of the production of local quality and export quality units of the highest manufacturing plant?
Answer (Detailed Solution Below)
Line Graph Question 10 Detailed Solution
Download Solution PDFCalculation:
Manufacturing capacity of plant A = 420 + 140 = 560
Manufacturing capacity of plant B = 350 + 150 = 500
Manufacturing capacity of plant C = 360 + 120 = 480
Manufacturing capacity of plant D = 440 + 80 = 520
Manufacturing capacity of plant E = 440 + 110 = 550
So,
Plant A has the highest manufacturing capacity.
In Plant A:
Local Quality = 420
Export Quality = 140
Thus,
Local quality : Export quality
⇒ 420 : 140 = 3 : 1
∴ The correct answer is option (1).
The line chart shows the annual food grain production for a country. For how many years was the production higher than the average production of the period?

the imports for year Y5 is Rs. 76000 crore, then what will be exports (in crores) for the year Y5?
Answer (Detailed Solution Below)
Line Graph Question 12 Detailed Solution
Download Solution PDFCalculation:
From the line chart,
Ratio of imports to exports in year Y5 = 0.95
⇒ Imports/Exports = 0.95
⇒ 76000/Exports = 0.95 = 95/100 = 19/20
⇒ Exports = 76000 × 20/19
∴ Exports = Rs. 80000 crore
The following line graph displays the ratio of exports to imports (in terms of money in ₹ crores) of company A from 2010 to 2015.
Study the graph carefully and answer the question based on the given line graph.
In how many years, the export of company A was more than the company's import?
Answer (Detailed Solution Below)
Line Graph Question 13 Detailed Solution
Download Solution PDFCalculation:
Ratio of export to import in 2010 = E : I = 9 : 10
Ratio of export to import in 2011 = E : I = 12 : 10
Ratio of export to import in 2012 = E : I = 7 : 10
Ratio of export to import in 2013 = E : I = 24 : 10
Ratio of export to import in 2014 = E : I = 35 : 10
Ratio of export to import in 2015 = E : I = 24 : 10
Hence, there are four observations in which the export of company A was more than the company A import
∴ The correct answer is four.
Based on the given graph, what is the percentage change in CO2 concentration from year 1995 to 2015?
Answer (Detailed Solution Below)
Line Graph Question 14 Detailed Solution
Download Solution PDFFrom the graph:
CO2 concentration in the year 1995 = 360
CO2 concentration in the year 2015 = 400
