Quantitative Aptitude: Data Interpretation Questions – Set 86

Questions (1-5): Study the following pie-chart and the table and answer the questions based on them.

  1. If the population of town C in 2012 is 25000, then what will be the population of town E below poverty line in that year?
    7736
    6950
    6475
    8125
    None
    Option D
    Solution:
    C in 2012
    10 ….. 25000
    13 ? ==>32500.
    E below poverty line
    100 ….. 32500
    25 ?==>8125.
  2. The ratio of population of town A below poverty line to that of town D below poverty line in 2012 is
    21:26
    14:17
    21:24
    18:21
    None
    Option A
    Solution:
    Let X be the total population of all the 6 towns.
    Then, population of town A below poverty line = 42% of (15% of X)
    population of town D below poverty line = 30% of (26% of X)
    ratio= 42% of (15% of X) / 30% of (26% of X)
    =21:26.
  3. Find the population of town A if the population of town C below poverty line in 2012 is 8000.
    28000
    30000
    25000
    24000
    None
    Option B
    Solution:
    C in below poverty
    40 … 8000
    100 ?==>20,000.
    Population in town A
    10 …. 20000
    15 ?==> 30,000.
  4. If in 2013, the population of town B and F increase by 10% each and the percentage of population below poverty line remains unchanged for all the town, then find the population of town F below poverty line in 2013, given that the population of town B in 2012 was 22000.
    4928
    5124
    5366
    4675
    None
    Option A
    Solution:
    B in 2012 is 22000
    Then F in 2012
    22 …. 22000
    14 ?==>14000.
    Both increased 10% in 2013
    B=24200
    F=15400
    F in Below poverty in 2013
    100…. 15400
    32 ?==> 4928.
  5. If the population of town A in 2012 is 30000, then what will be the population of town B in that year?
    42000
    44000
    50000
    35000
    None
    Option B
    Solution:
    A in 2012
    15 …. 30000
    22 … ?==> 44000.

Directions (6-10) Study the following graph carefully to answer the questions that follow

The following line graph gives distance (in km) travelled by five different cars in a day.

  1. What is the respective ratio of the distance travelled by car B to the distance travelled by car D?
    2:3
    3:2
    4:5
    5:4
    None
    Option C
    Solution:
    B:D
    =400:500
    4:5.
  2. What is the average distance travelled by all the cars together ?
    310
    340
    320
    360
    None
    Option D
    Solution:
    350+400+250+500+300=1800

    43%
    36.2%
    46.6%
    34%
    None
    Option C
    Solution:
    C+D=250+500=750
    750 100
    350 ?==>700/15=46.6%
  5. If the time taken by car E to cover the given distance was10 hours, what was the average speed of the car ?
