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.

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"

Preeti said:   1 decade ago
Why not take the 98-99 amount of 3120?

Amit said:   1 decade ago
Can anyone give easier method for this?

Yogesh said:   1 decade ago
There is need of find % of 1993-94 but they have calculated 1997-98 so, please make it eliminate by 1993-94
Thanx

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

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