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.

How did you get the denominator?

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

Why we are not comparing 93 and 94, 94 and 95?

Pooja said:   2 years ago
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.
