AAO Exam-CT 10: Quant (DI - Line Graph)

1. Directions: Study the chart and answer the following questions.

The line graph show number of Jio and Airtel users in 5 different states.

Question:

How many total Airtel users are there in all five states together?

  • 1250
  • 1200
  • 1150
  • 1000
  • None of these

Given:

Number of Airtel users in UP = 250

Number of Airtel users in Uttarakhand = 200

Number of Airtel users in Himachal = 150

Number of Airtel users in Haryana = 350

Number of Airtel users in Delhi = 250

Calculations:

Total Airtel users in all five states together = 250 + 200 + 150 + 350 + 250

⇒ 1200

∴ Total Airtel users in all five states together are 1200

2. Directions: Study the chart and answer the following questions.

The line graph show number of Jio and Airtel users in 5 different states.

Question:
What is the average of Jio users in Delhi, Uttarakhand and Haryana?
  • 900
  • 300
  • 600
  • 200
  • None of these

Given:

Number of Jio users in Delhi = 350

Number of Jio users in Uttarakhand = 300

Number of Jio users in Haryana = 250

Formula used:

Average = Sum of values/Number of values

Calculations:

Average of Jio users in Delhi, Uttarakhand and Haryana = (350 + 300 + 250)/3

⇒ 900/3

⇒ 300

∴ The average of Jio users in Delhi, Uttarakhand and Haryana is 300

3. Directions: Study the chart and answer the following questions.

The line graph show number of Jio and Airtel users in 5 different states.

Question:

What is the ratio of Jio users in Delhi to Airtel users in UP?

  • 8 : 5
  • 5 : 8
  • 7 : 5
  • 5 : 7
  • None of these

Given:

Number of Jio users in Delhi = 350

Number of Airtel users in UP = 250

Calculations:

Ratio of Jio users in Delhi to Airtel users in UP = 350 : 250

⇒ 7 : 5

∴ The ratio of Jio users in Delhi to Airtel users in UP is 7 : 5

4. Direction: Following line graph shows the number of bikes sold by different companies in different years.

Question:
If price of Honda bike is 20% more than that of hero bike so what is ratio of revenue generated by Honda to hero in year 2017?
  • 3 : 8
  • 5 : 7
  • 6 : 1
  • 5 : 3
  • 4 : 3

Let the price of hero bike be 100a so, price of Honda bike is 120a

Revenue generated by hero bike in 2017 = 100a × 180

Revenue generated by Honda bike in 2017 = 120a × 200

∴ according to question

120a × 200 : 100a × 180

⇒ required ratio 4 : 3

5. Direction: Following line graph shows the number of bikes sold by different companies in different years.

Question:
if bikes sold in 2018 is 20% less than the bikes sold in 2020. Find the number of bikes sold in 2020?
  • 650
  • 750
  • 800
  • 900
  • 850

Bikes sold in 2018 = 160 + 240 + 200 = 600

⇒ Required solution = 600/(100 – 20) × 100

600/80 × 100 = 750

6. Direction: Following line graph shows the number of bikes sold by different companies in different years.

Question:
What is the ratio of bikes sold in the year 2016 to the bikes sold in the year 2019?
  • 24 : 31
  • 23 : 30
  • 31 : 11
  • 31 : 24
  • none of these

Bikes sold in year 2016 = 220 + 250 + 150 = 620

Bikes sold in year 2019 = 120 + 200 + 160 = 480

∴ Required ratio = 31 : 24

7. Direction: Following line graph shows the number of bikes sold by different companies in different years.

Question:
Bikes sold by hero and Bajaj together in the year 2016 is how much percent more/less than the number of Bajaj bikes sold in 2017.
  • 30%
  • 45%
  • 33.33%
  • 50%
  • 20%

Bikes sold by hero in 2016 = 250

Bikes sold by Bajaj in 2016 = 150

Sum of bikes sold by hero and Bajaj in 2016 = 250 + 150 = 400

Bikes sold by Bajaj in 2017 = 300

∴ Required percentage = (400 – 300)/300 × 100 = 1/3 × 100 = 33.33%

8. Directions: Study the following data and answer the following questions:

Following line graph shows the literate and illiterate population of five villages.

Total population = literate population + illiterate population

Question:
Find the ratio between the total population of village N and village R.
  • 1 : 3
  • 6 : 7
  • 9 : 1
  • 5 : 8
  • 8 : 9

Given:

Total population of village N = 600 + 900 = 1500

Total population of village R = 1400 + 1000 = 2400

Required ratio =

= 1500 : 2400

= 5 : 8

9. Directions: Study the following data and answer the following questions:

Following line graph shows the literate and illiterate population of five villages.

Total population = literate population + illiterate population

Question:
The literate population of village Q is approximately what percent of the total population of village Q?
  • 75%
  • 55%
  • 65%
  • 60%
  • 70%

Given:

Total population of village Q = 1200 + 800 = 2000

Total literate population of village Q = 1200

Required percentage =

= 1200/2000 × 100

= 60%

10. Directions: Study the following data and answer the following questions:

Following line graph shows the literate and illiterate population of five villages.

Total population = literate population + illiterate population

Question:
Find the average Literate population of five villages.
  • 1100
  • 1200
  • 1250
  • 1360
  • 1040

Given:

Total literate population of five villages =

= 900 + 600 + 1100 + 1200 + 1400 = 5200
