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.
1997
1998
1999
2000
Correct answer is A
Percentage change (rise/fall) in the production of Company Y in comparison to the previous year, for different years are:
For 1997 = [ (35 - 25)/25 x 100 ] % = 40%
For 1998 = [ (35 - 35)/35 x 100 ] % = 0%
For 1999 = [ (40 - 35)/35 x 100 ] % = 14.29%
For 2000 = [ (50 - 40)/40 x 100 ] % = 25%
Hence, the maximum percentage rise/fall in the production of Company Y is for 1997.
The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.
What was the percentage increase in the foreign exchange reserves in 1997-98 over 1993-94?
100
150
200
620
Correct answer is A
Foreign exchange reserves in 1997 - 1998 = 5040 million US $.
Foreign exchange reserves in 1993 - 1994 = 2520 million US $.
Therefore Increase = (5040 - 2520) = 2520 US $.
Therefore Percentage Increase = ( 2520/2520 x 100 ) % = 100%.
The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.
95%
110%
115%
125%
Correct answer is D
Average foreign exchange reserves over the given period = [ 1/8 x (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) ] million US $ = 3480 million US $.
Foreign exchange reserves in 1996 - 1997 = 4320 million US $.
Therefore Required percentage = ( 4320/3480 x 100 ) % = 124.14% ≈ 125%.
The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.
1992-93
1993-94
1994-95
1996-97
Correct answer is A
There is an increase in foreign exchange reserves during the years 1992 - 1993, 1994 - 1995, 1996 - 1997, 1997 - 1998 as compared to previous year (as shown by bar-graph).
The percentage increase in reserves during these years compared to previous year are:
For 1992 - 1993 = [ (3720 - 2640)/2640 x 100 ] % = 40.91%.
For 1994 - 1995 = [ (3360 - 2520)/2520 x 100 ] % = 33.33%.
For 1996 - 1997 = [ (4320 - 3120)/3120 x 100 ] % = 38.46%.
For 1997 - 1998 = [ (5040 - 4320)/4320 x 100 ] % = 16.67%.
Clearly, the percentage increase over previous year is highest for 1992 - 1993.

The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999.
2:6
3:4
3:5
4:4
Correct answer is 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, i.e., for 3 years and below 3480 million US $ during the years 1991-92, 1993-94, 1994-95, 1995-56 and 1998-99 i.e., for 5 years.
Hence, required ratio = 3 : 5
The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.
Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.
Total sales of branches B1, B3 and B5 together for both the years (in thousand numbers) is?
250
310
435
560
Correct answer is D
Total sales of branches B1, B3 and B5 for both the years (in thousand numbers)
= (80 + 105) + (95 + 110) + (75 + 95)
= 560.

80
83
88
Correct answer is B
Average sales of all the six branches (in thousand numbers) for the year 2000
= 1/6 x [80 + 75 + 95 + 85 + 75 + 70] = 80.
The bar graph given below shows the sales of books (in thousand number) from six branches of a publishing company during two consecutive years 2000 and 2001.
Sales of Books (in thousand numbers) from Six Branches - B1, B2, B3, B4, B5 and B6 of a publishing Company in 2000 and 2001.
75%
77.5%
82.5%
87.5%
Correct answer is D
Average sales (in thousand number) of branches B1, B3 and B6 in 2000
= 1/3 x (80 + 95 + 70) = ( 245/3 )
Average sales (in thousand number) of branches B1, B2 and B3 in 2001
= 1/3 x (105 + 65 + 110) = ( 280/3 )
Therefore Required percentage = [ (245/3)/(280/3) x 100 ] % = ( 245/280 x 100 ) % = 87.5%

Correct answer is C
Required percentage
= [ (70 + 80)/(95 + 110) x 100 ] %
= [ 150/205 x 100 ] %
= 73.17%.
