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.

6. 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.
   
7. 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
   Average=1800/5=360.
   
8. If car C covered the given distance at the average speed of 50 km/hr, what was the time taken by it to cover this distance?
   8hrs
   5hrs
   6hrs
   4hrs
   None
   Option B
   Solution:
   Car C time taken =250/50
   =5hrs.
   
9. The distance traveled by car A is approximately what per cent of the total distance travelled by car D and C together ?
   43%
   36.2%
   46.6%
   34%
   None
   Option C
   Solution:
   C+D=250+500=750
   750 100
   350 ?==>700/15=46.6%
