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.
Production of Paper (in lakh tonnes) by Three 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%.
