c) 1:1
d) cannot be determined

Solutions for CAT Data Interpretation Practice Questions Set-2:

Solutions (1 – 5):

In 2011
Production = 200, Exports = 110 so consumption = 90
In 2012
Production = 240, Exports = 130 so consumption = 120
In 2013
Production = 220, Exports = 120 so consumption = 100
In 2014,
Production = 300, Exports = 170 so consumption = 130
In 2015
Production = 250, Exports = 140 so consumption = 110
Clearly the required ratio is highest for 2014.

In 2011
Production = 200
In 2012
Production = 240
In 2013
Production = 220
In 2014,
Production = 300
In 2015
Production = 250
So the percentage change in production is highest for the year 2014.

Population = Consumption/per capita consumption
In 2011
Consumption = 90, Per capita consumption = 40
In 2012
Consumption = 120, Per capita consumption = 50
In 2013
Consumption = 100, Per capita consumption = 40
In 2014,
Consumption = 130, Per capita consumption = 30
In 2015
Consumption = 110, Per capita consumption = 50
Clearly, this ratio is highest for the year 2014.

In 2013
Consumption = 100, Per capita consumption = 40
So required population = 100/40 = 2.5 million.

In 2011
Production = 200, Exports = 110 so consumption = 90
In 2012
Production = 240, Exports = 130 so consumption = 110
In 2013
Production = 220, Exports = 120 so consumption = 100
In 2014,
Production = 300, Exports = 170 so consumption = 130
In 2015
Production = 250, Exports = 140 so consumption = 110
So the percentage change in consumption is highest for the year 2014.

Solutions (6 – 10):

From the given graph, the percentage increase in Mercury automatic cars in 2012 is 20% and that of Venus automatic cars is 30%. Let the number of Mercury automatic cars in 2011 be x and the number of Venus automatic cars in 2012 be y. Thus, total number of automatic cars in 2011 = x + y. Given, total number of automatic cars increases by 23.33% in 2012.

Thus, total number of automatic cars in 2012 = 1.233(x + y) = 1.2x + 1.3y

.05x = .1y

=> x = 2y. Thus, the number of automatic Mercury cars in 2011 is twice that of Venus automatic cars. Let, the number of Mercury automatic cars in 2011 be 100k and Venus automatic cars be 50k. Using information from the given chart, the following table can be formed:

From the table, we can see that the number of Semi-Automatic cars of Mercury sold was greater than the number of Semi-Automatic cars of Venus in 2011 and 2015. Thus, B is the right choice.

Total number of Semi-Automatic cars sold by AUXN in 2012 = 30k + 35k = 65k
Total number of cars sold by AUXN in 2012 = 150k + 100k = 250k
Thus, the required percentage = $$\frac{65}{250}\times100$$% = 26%

The total number of cars sold was less only in 2012. Thus, B is the right choice.

Thus, the required percentage increase = $$\frac{50k – 30k}{30k}\times100$$% = 66.67%
