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?

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"

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"

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

ie. 3360-2520 X 100

2520- how do you get this number here?

ie. 3360-2520 X 100

2520- how do you get this number here?
