Introduction to Data Interpretation
Direction: Study the following bar–diagram carefully and answer the questions.

-
View Hint View Answer Discuss in Forum
According to given bar graph , we have
The foreign reserves in 2012 = 5040
The foreign reserves in 2008 = 2520
Increase = 5040 - 2520 = 2520Required percentage increase = Increase × 100 The foreign reserves in 2008
Correct Option: A
According to given bar graph , we have
The foreign reserves in 2012 = 5040
The foreign reserves in 2008 = 2520
Increase = 5040 - 2520 = 2520Required percentage increase = Increase × 100 The foreign reserves in 2008 Required percentage increase = 2520 × 100 = 100% 2520

On the basis of given graph in question ,
The foreign exchange reserve in 2012 = 5040
The foreign exchange reserve in 2009 = 3360Required answer = The foreign exchange reserve in 2012 The foreign exchange reserve in 2009
Correct Option: D
On the basis of given graph in question ,
The foreign exchange reserve in 2012 = 5040
The foreign exchange reserve in 2009 = 3360Required answer = The foreign exchange reserve in 2012 The foreign exchange reserve in 2009 Required answer = 5040 = 1.5 3360
Direction: The bar graph given below shows the per acre yield (in kg) of different countries. Study the graph carefully and answer the questions.
- Writing the yields of all countries in ascending order, the difference between the sum of yields of first three countries to that of last three countries is
-

From the given bar diagram , we see
Ascending order of yield per acre : 80 < 120 < 120 < 132 < 160 < 200
Sum of yields of first three countries = 132 + 160 + 200 = 492
Sum of yields of last three countries = 80 + 120 + 120 = 320
Required difference = Sum of yields of first three countries - Sum of yields of last three countriesCorrect Option: C
From the given bar diagram , we see
Ascending order of yield per acre : 80 < 120 < 120 < 132 < 160 < 200
Sum of yields of first three countries = 132 + 160 + 200 = 492
Sum of yields of last three countries = 80 + 120 + 120 = 320
Required difference = Sum of yields of first three countries - Sum of yields of last three countries
∴ Required difference = (492 – 320) kg. = 172 kg.
- Sri Lanka’s yield (approximately) is what percent of total yield of all the countries?
-
View Hint View Answer Discuss in Forum
On the basis of given graph in question ,
Total yield of all the countries = 80 + 120 + 132 + 120 + 160 + 200 = 812
The per acre yield of Sri Lanka = 132Required percent = The per acre yield of Sri Lanka × 100 Total yield of all the countries
Correct Option: B
On the basis of given graph in question ,
Total yield of all the countries = 80 + 120 + 132 + 120 + 160 + 200 = 812
The per acre yield of Sri Lanka = 132Required percent = The per acre yield of Sri Lanka × 100 Total yield of all the countries Required percent = 132 × 100 ≈ 16.2 812
- By how much percent is India’s per acre yield more than that of Pakistan’s?
-
View Hint View Answer Discuss in Forum
According to given bar graph , we have
The per acre yield of India = 200
The per acre yield of Pakistan = 160
Change in acre yield = 200 - 160 = 40Required percent = Change in acre yield × 100 The per acre yield of Pakistan
Correct Option: B
According to given bar graph , we have
The per acre yield of India = 200
The per acre yield of Pakistan = 160
Change in acre yield = 200 - 160 = 40Required percent = Change in acre yield × 100 The per acre yield of Pakistan Required percent = 40 × 100 = 25% 160
