Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
1996
1997
1998
1999
Correct answer is A
The percentage increase in the amount invested in raw-materials as compared to the previous year, for different years are:
For 1996 = [ (225 - 120)/120 ] % = 87.5%
For 1997 = [ (375 - 225)/225 ] % = 66.67%
For 1998, there is a decrease.
For 1999 = [ (525 - 330)/330 ] % = 59.09%
For 2000, there is a decrease.
Therefore, there is maximum percentage increase in 1996.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
1996
1997
1998
1999
Correct answer is B
The percentage change in the amount invested in raw-materials and in the value of sales of finished goods for different years are:
Percentage change in Amount invested in raw-material:
For 1996 = [ (225 - 120)/120 x 100 ] % = 87.5%
For 1997 = [ (375 - 225)/225 x 100 ] % = 66.67%
For 1998 = [ (330 - 375)/375 x 100 ] % = -12%
For 1999 = [ (525 - 330)/330 x 100 ] % = 59.09%
For 2000 = [ (420 - 525)/525 x 100 ] % = -20%
Percentage change in value of sales of finished goods:
For 1996 = [ (300 - 200)/200 x 100 ] % = 50%
For 1997 = [ (500 - 300)/300 x 100 ] % = 66.7%
For 1998 = [ (400 - 500)/500 x 100 ] % = -20%
For 1999 = [ (600 - 400)/400 x 100 ] % = 50%
For 2000 = [ (460 - 600)/600 x 100 ] % = -23.33%
Thus, the percentage difference is same during the year 1997.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
Rs. 62.5 lakhs
Rs. 68.5 lakhs
Rs. 71.5 lakhs
Rs. 77.5 lakhs
Correct answer is D
Required difference
= Rs. [ 1/6 x (200 + 300 + 500 + 400 + 600 +460) - 1/6 x (120 + 225 + 375 + 330 + 525 + 420) ] lakhs
= Rs. [ ( 2460/6 ) - ( 1995/6 ) ] lakhs
= Rs. (410 - 332.5) lakhs
= Rs. 77.5 lakhs.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
33%
37%
45%
49%
Correct answer is D
Required percentage = [ 600/(375 + 330 + 525) x 100 ] %
= 48.78%
≈ 49%.
Out of the two bar graphs provided below, one shows the amounts (in Lakh Rs.) invested by a Company in purchasing raw materials over the years and the other shows the values (in Lakh Rs.) of finished goods sold by the Company over the years.
1995
1996
1997
1998
Correct answer is C
The differences between the amount invested in raw material and the value of sales of finished goods for various years are:
For 1995 = Rs. (200 - 120) lakhs = Rs. 80 lakhs.
For 1996 = Rs. (300 - 225) lakhs = Rs. 75 lakhs.
For 1997 = Rs. (500 - 375) lakhs = Rs. 125 lakhs.
For 1998 = Rs. (400 - 330) lakhs = Rs. 70 lakhs.
For 1999 = Rs. (600 - 525) lakhs = Rs. 75 lakhs.
For 2000 = Rs. (460 - 420) lakhs = Rs. 40 lakhs.
Clearly, maximum difference was during 1997.
The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years.
Production of Paper (in lakh tonnes) by Three Companies X, Y and Z over the Years.
What is the difference between the production of Company Z in 1998 and Company Y in 1996?
200,000 tons
2,000,000 tons
20,000 tons
20,000,000 tons
Correct answer is B
Lakh tonne = 100,000
Therefore required difference = [(45 - 25) x 100,000] tons = 2,000,000 tons.
The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years.

What is the percentage increase in the production of Company Y from 1996 to 1999?
30%
45%
50%
60%
Correct answer is D
Percentage increase in the production of Company Y from 1996 to 1999
= [ (40 - 25)/25 x 100 ] %
= [ 15/25 x 100 ] %
= 60%.

1996
1997
1998
1999
Correct answer is A
The percentages of production of Company Z to the production of Company Z for various years are:
For 1996 = ( 35/25 x 100 ) % = 140%
For 1997 = ( 40/35 x 100 ) % = 114.29%
For 1998 = ( 45/35 x 100 ) % = 128.57%
For 1999 = ( 35/35 x 100 ) % = 87.5%
For 2000 = ( 35/35 x 100 ) % = 70%
Clearly, this percentage is highest for 1996.
The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years.
Production of Paper (in lakh tonnes) by Three Companies X, Y and Z over the Years.
The average production for five years was maximum for which company?
X
Y
Z
both X and Z
Correct answer is D
Average production (in lakh tons) in five years for the three companies are:
For Company X = [ 1/5 x (30 + 45 + 25 + 50 + 40) ] = 190/5 = 38
For Company Y = [ 1/5 x (25 + 35 + 35 + 40 + 50) ] = 185/5 = 37
For Company Z = [ 1/5 x (35 + 40 + 45 + 35 + 35) ] = 190/5 = 38
Therefore Average production of five years is maximum for both the Companies X and Z.
The bar graph given below shows the data of the production of paper (in lakh tonnes) by three different companies X, Y and Z over the years.
Production of Paper (in lakh tonnes) by Three Companies X, Y and Z over the Years.
1:1
15:17
23:25
27:29
Correct answer is C
Average production of Company X in the period 1998-2000
= [ 1/3 x (25 + 50 + 40) ] = ( 115/3 ) lakh tons
Average production of Company Y in the period 1998-2000
= [ 1/3 x (35 + 40 + 50) ] = ( 125/3 ) lakh tons
Therefore Required ratio = (115/3)/(125/3) = 115/125 = 23/25
