Solutions for CAT Previous Year Data Interpretation Questions:
Solutions (1 – 5):
1) Answer (D)
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.
2) Answer (C)
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.
3) Answer (A)
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.
4) Answer (A)
In 2013
Consumption = 100, Per capita consumption = 40
So required population = 100/40 = 2.5 million.
5) Answer (B)
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.
