Data interpretation -Bar graph data Interpretation questions

Question1:The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991-92 to 1998-99. Answer the questions based on this graph.

1.The foreign exchange reserves in 1997-93 was how many times that in 1994-95 ?

• (a) 0.7
• (b) 1.2
• (c) 1.4
• (d) 1.5
• (e) 1.8 1

2.What was the percentage increase in the foreign exchange reserves in 1997-98 over

• 1993-94 ?
• (a)100
• (b)150
• (c)200
• (d)620
• (e)2520

3.For which year, the percent increase of foreign exchange reserves over the previous-year,is the highest?

• (a)1992-93
• (b)1993-94
• (c)1994-95
• (d)1996-97
• (e)1997-98

4. The foreign exchange reserves in 1996-97 were approximately what percent of the average foreign exchange reserves over the period under review ? ,

• (a) 95%
• (b) 110%
• (c) 115%
• (d) 125%
• (e) 140%

5, The ratio of the number of years, in which the foreign exchange reserves are above the

average reserves, to those in which the reserves are below the average reserves, is :

• (a)2:6
• (b)3:4
• (c)3:5
• (d)4;4
• (e)5:3

Solutions:

Sol. 1.(d) : Required ratio = 5040/3360=1.5

Sol.2. (a). Foreign exchange reseryes in 1997-98 = 5040 million US $

Foreign exchange reserves in 1993-94 = 2520 million US $

Increase = (5040 — 2520) = 2520 million US $.

Percentage increase =[ (2520/2520) x 100)]% = 100%.

Sol.3. (a) : There is an increase in foreign exchange reserves during the years 1992-93,

1994-95 1996-97 and 1997-98 as compared to previous year (as shown by

bar-graph).

The percentage increase in reserves during these years compared to previous

year are :

(i) For 1992-93 =[{(3720-2640)/2640 }* 100] % = 40.91%

(ii) F01‘ 1994-95 =[{(3360 - 2520)/2520}* 100] % = 33.33%

(iii) For 1996-97 =[{(4320 - 3120)/3120}*100] % = 38.46%

(iv) For 1997-98 =[{ (5040 - 4320)/4320}*100] % = 16.67%

Clearly, the percentage increase over previous year is highest for 1992-93.

Sol.4. (d) : Average foreign exchange reserves over the given period

= [(2640 + 3720 + 2520 + 3360 + 3120+ 4320 + 5040 + 3120)] million US $

= 3480 million US $.

Foreign exchange reserves in 1996-97 = 4320 million US $.

Required Percentage = [( 4320/3480)*100)]% = 124.14% = 125%.

Sol.5. (c)Average foreign exchange reserves over the given period = 3480 million US$.

The country had reserves above 3480 million US $ during the years 1992-93, 1996-97 and 1997-98 ie., for 3 years and below 3480 million US$ during the years 1991-92, 1993-94, 1994-95, 1995-96 and 1998-99 ie., for5 years.

Hence, required ratio = 3 :5

4.What  is the ratio of the total sales of’ branch B2 for -both years to the total sales of

branch B4 for both years ?

• (a)2:3 
• (b)3:5
• (c)425
• (d)5:7
• (e)7:9

5.What percent of the average sales of branches Bl, B2 and B3 in 2001 is the average sales of branches B1, B3 and B6 in 2000 ?

• (a) 75%
• (b) 77.5%
• (c) 82.5%
• (d) 85%
• (e) 87.5%

Solutions:

Sol. 1. (d) : Total sales of branches B1, B3 and B5 for both the years (in thousand numbers) = (80 + 105) + (95 + 110) + (75+ 95) = 560.

Sol. 2. (c) : Required Percentage =  [{(70+80)/(95+110)} *100]% = 73.17%.

Sol.3. (b) : Average sales of all the ,six branches (in thousand numbers) for the year 2000 = (1/6)*[80+ 75 +95 + 85+ 75 + 70] = 80.

Sol.4.(e) : Required [(75+65)/(85+95)]=7/9

Sol.5.(e): Average sales (in thousand numbers) of branches B1, B3 and B6 in 2000

=(1/3)*(8O+95+7O)=245/3

Average sales (in thousand numbers) of branches B1, B2 and B3 in 2001

(1/3)*(105+65+110) =280/3

Required Percentage =[(245/3)/(280/3)]*100% = 87.5%

• (e) 42000

3.The percentage of 4AH batteries sold to the total number of batteries sold was

maximum in the year :

• (a) 1994
• (b) 1995
• (c) 1996
• (d) 1997
• (e) 1998

4.In the case of which battery there was a continuous decrease in sales from 1992 to 1997 ? -

• (a) 4AH
• (b) 7AH
• (c) 32AH
• (d) 35AH
• (e) 55AH

5.What was the approximate percentage increase in the sales of 55AH batteries in 1998

compared to that in 1992 ?

• (a) 28%
• (b) 31%
• (C) 33%
• (d) 34%
• (e) 37%

Solutions:

Sol. 1. (c) : The total sales (in thousands) of all the seven years for various batteries are :

For 4AH= 75 + 90 + 96 + 105+ 90 + 105 + 115 = 676

For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694

For 32AH = 114 + 103 + 75 +‘150 + 135 + 165 + 160 = 901

For 35AH= 102+84+105+90+75+45+100=-601

For 55 AH = 108 + 126 +1135 + 75 + 90 + 120 + 145 = 799.

Clearly, sales. are maximum in case of 32AH batteries.

Sol.2. (d) : Required difference = [(84 - 45) * 1000] = 39000.

Sol.3. (d) : The percentages of sales of 4AH batteries to the total sales in different

years are : -

For 1992 = [(75/543) * 100]% = 13.81%;

For 1993 = [(90/528*100]% =17.05%

For 1994=[(96/525)*100]%=18.29%

For 1995=[(105/510)*100]%=20.59%

For 1996=[(96/465)*100]%=19.35%

For 1997=[(105/495)*100]%=21.21%

For 1998=[(115/605)*100]%=19.01%

Clearly percentage is maximum in the year 1997.

Sol.4.(b)From the table it is clear that the sales of 7AH batteries have been decreasing continuously from 1992 to 1997.

Sol.5.(d) :Required Percentage =[{(145-108)/108}*100]%=34.26%

Question2.The following table gives the percentage of marks obtained by seven students in six different subjects in an examination. Study the table and answer the questions based on it. The numbers in the bracket give the maximum mark in each subject

 1. What was the aggregate of marks obtained by Sajal in all the six subjects ?

• (a) 409
• (b) 419
• (c) 429
• (d) 439
• (e) 449

2. What is the overall percentage of Tarun ? .

• (a) 52.5%
• (b) 55%
• (c) 60%
• (d) 63%
• (e) 64.5%

3. What are the average marks obtained by all the seven students in Physics ? (rounded off to two digits after decimal)

• (a) 77.26  
• (b) 89.14  
• (c) 91.37
• (d) 96.11
• (e) 103.21

4. The number of students who obtained 60% and above marks in all the subjects is :

• (a) 1
• (b) 2
• (c)3
• (d) None
• (e) None of the above

5. In which subject is the overall percentage the best ?

• (a)History
• (b) Maths
• (c) Physics
• (d) Chemistry
• (e) Geography

Solutions:

Sol.1. (e) : Aggregate marks obtained by Sajal

= [(90% of 150) + (60% of 130) + (70% of 120) + (70% of 100) + (90% of 60)+ (70% of 40)] = 135 + 78 + 84 + 70 + 54 + 28 = 449.

Sol.2.(c) : Aggregate marks obtained by Tarun= [(65% of 150)'+ (35% of 130) + (50% of'120) + (77% of 100) + (80% of 60)+ (80% of 40)] = 97.5 + 45.5 + 60 + 77 + 48 + 32 = 360.

Total maximum marks (of all the six subjects) = (150 + 130 + 120 + 100 + 60 + 40) = 600.

Overall percentage of Tarun =  [(360/600)*100]% = 60%

Sol.3.(b) : Average marks obtained in Physics by all the seven students

= (1/7) * [(90% of 120)+ (80% of 120) + (70% of 120) + (80% of 120)+ (85% of 120)+ (65% of 120)+ (50% of 120))=89.14

Sol.4.(b). From the ‘table it is clear that Sajal and Rohit have 60% or more marks in each of the six subjects.

Sol.5.(b). We shall find the overall percentage (for all the seven students) with respect to each subject.

The overall percentage for any subject is equal to the average of percentage obtained by all the seven students since the maximum marks for any subject is the same for all the students. 

Therefore, Overall percentage for :

(i) Maths = [(1/7)*(90 + 100 + 90 + 80 + 80 + 70 + 65)]%= 82.14%.

(ii) Chemistry = [(1/7)* (50 + 80 + 60 + 65 + 65 + 75 + 35)]%= 61.43%.

(iii) Physics = [(1/7)*(90 + 80 + 70 + 80 + 85 + 65 + 50)]%=74.29%.

(iv) Geography =  [(1/7)* (60 +,40+ 70 + 80 + 95 + 85 + 77)]%= 72.43%.

(v) History =[(1/7)*(70 + 80 + 90 + 60 + 50 + 40 + 80)%=67.14%

(vi) Computer Science =(80+70+70+60+90+60+80)]%=72.86

Clearly percentage is highest for maths.
