Latest Line Graph MCQ Objective Questions

Line Graph Question 1:

Comprehension:

Directions: Study the following line graph and answer the questions based on it

Find the percentage increase in total sales done in 2000 in comparison to 1998.

  1. 47
  2. 120 
  3. 147
  4. 160

Answer (Detailed Solution Below)

Option 3 : 147

Line Graph Question 1 Detailed Solution

Total sales in 2000 = sale of Nokia in 2000 + sale of Samsung in 2000

and

Total sales in 1998 = sale of Nokia in 1998 + sale of Samsung in 1998

so

Total sales in 2000 = 220 + 225 = 445

Total sales in 1998 = 120 + 60 = 180

% increase = Increase/Original Value

Increase = Value(2000) – Value(1998)

⇒ Increase = 445 – 180 = 265

∴ %increase = (265/180) × 100 = 147%

Line Graph Question 2:

Comprehension:

Directions: Study the following line graph and answer the questions based on it

In which of the following years the total sales done by both the companies together was the highest?

  1. 1998
  2. 1999
  3. 2000
  4. 2001

Answer (Detailed Solution Below)

Option 2 : 1999

Line Graph Question 2 Detailed Solution

In Year 1998, Total Sales Done = 120 + 60 = 180

In Year 1999, Total Sales Done = 180 + 320 = 500 → Maximum

In Year 2000, Total Sales Done = 225 + 220 = 445

In Year 2001, Total Sales Done = 160 + 200 = 360

∴ Sales done was highest in Year 1999

Line Graph Question 3:

Comprehension:

Directions: Study the following line graph and answer the questions based on it

What is the average number of mobiles phones (in thousands) sold by Nokia and Samsung over the years?

  1. 120
  2. 143
  3. 172
  4. 371.25

Answer (Detailed Solution Below)

Option 4 : 371.25

Line Graph Question 3 Detailed Solution

Average = Sum/Number of terms

Average = (120 + 60 + 180 + 320 + 225 + 220 + 160 + 200)/4 = 1485/4

∴ Average = 371.25

Line Graph Question 4:

Comprehension:

Directions: Study the following line graph and answer the questions based on it

What is the respective ratio of the numbers of mobile phones sold by Nokia and Samsung in 2000?

  1. 45 : 44
  2. 44 : 45
  3. 225 : 120
  4. 120 : 225

Answer (Detailed Solution Below)

Option 1 : 45 : 44

Line Graph Question 4 Detailed Solution

Number of mobile phones sold by Nokia in 2000 = 225

Number of mobile phones sold by Samsung in 2000 = 220

∴ Ratio = 225 : 220 = 45 : 44

Line Graph Question 5:

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.

Vivo phones sold in July is how much percent less than the number of Nokia phones sold in April? 

  1. 18%
  2. 50%
  3. 72%
  4. 30%
  5. None of the above

Answer (Detailed Solution Below)

Option 4 : 30%

Line Graph Question 5 Detailed Solution

Given:

Number of phones sold by Nokia in April = 500

Number of phones sold by Vivo in July = 350

Calculation:

Difference b/w the number of phones sold by Nokia and Vivo in the month of April and July = (500 ─ 350) = 150

Required percentage = (150/500) × 100% = 30%

∴ Vivo phones sold in July is 30% less than the number of Nokia phones sold in April

GIVEN:

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

Calculation:

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%

Download Solution PDF

Given:

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

Line Graph Question 10 Detailed Solution

Download Solution PDF

Calculation:

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).

Calculation:

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

Download Solution PDF

Calculation:

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?

  1. 11.00%
  2. 11.31%
  3. 11.26%
  4. 11.11%

Answer (Detailed Solution Below)

Line Graph Question 14 Detailed Solution

Download Solution PDF

From the graph:

CO2 concentration in the year 1995 = 360

CO2 concentration in the year 2015 = 400

Hence,

Percentage change = [(400 – 360)/360] × 100

⇒ 40/360 × 100

⇒ 1/9 × 100 = 11.11%

∴ The percentage change in COconcentration is 11.11%.
