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.
