Foreign Exchange Reserves Of a Country. (in million US $)


3.
For which year, the percent increase of foreign exchange reserves over the previous year, is the highest?
1992-93
1993-94
1994-95
1996-97
Answer: Option
Explanation:

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.

Here we compare the increase percentage with previous year,

So find the difference between previous year, and the year which we are going to compare, and then divide it with the previous year foreign exchange reserve (because here we want to know how many percentage the foreign exchange will increased compare to the previous year).

Preethi 98-99 previous year is 97-98 .
98-99 is 3120 and 97-98 is 5040.
5040 is greater than 3120 so we do not take 98-99(3120).
As its given in question , " the percent increase of foreign exchange reserves over the previous year, is the highest"

1992-93.
1993-94.
1994-95.
1996-97.

In question, they have asked about the above years.
In explanation, year93-94 is skipped and instead, 97-98 is taken
Is my interpretation wrong? Anyone, please clarify this.

During calculations, how do you manage to get the denominator?

ie. 3360-2520 X 100
2520- how do you get this number here?

Alon lee said:   6 years ago
How did you get the denominator?

Let's take (3720-2640)/2640 X 100,
How did you find the denominator 2640?
Please tell me.
