Question: 2 -
The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991 - 1992 to 1998 - 1999. Foreign Exchange Reserves Of a Country. (in million US $) 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?
-
4:4
-
3:5
-
3:4
-
2:6
Answer:
3:5
Solution:
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.
Average foreign exchange reserves over the given period = 3480 million US $.

Question: 3 -
For which year, the percent increase of foreign exchange reserves over the previous year, is the highest?
-
1994-95
-
1993-94
-
1992-93
-
1996-97
Answer:
1992-93
Solution:
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)
x 100
% = 40.91%.
2640
For 1994 - 1995 =
(3360 - 2520)
x 100
% = 33.33%.
2520
For 1996 - 1997 =
(4320 - 3120)
x 100
% = 38.46%.
3120
For 1997 - 1998 =
(5040 - 4320)
x 100
% = 16.67%.
4320
Clearly, the percentage increase over previous year is highest for 1992 - 1993.
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) | x 100 | % = 40.91%. | ||
2640 |
For 1994 - 1995 = | (3360 - 2520) | x 100 | % = 33.33%. | ||

-
95%
-
110%
-
125%
-
115%
Answer:
125%
Solution:
Average foreign exchange reserves over the given period
=
1
x (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120)
million US $
8
= 3480 million US $.
Foreign exchange reserves in 1996 - 1997 = 4320 million US $.
Required percentage =
4320
x 100
% = 124.14% 125%.
3480
Average foreign exchange reserves over the given period
= | 1 | x (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) | million US $ | ||
8 |
= 3480 million US $.
Foreign exchange reserves in 1996 - 1997 = 4320 million US $.
