So lets calculate the percentage increase of these years compared to previous years :

i. For year 1992-93 =3720−26402640∗100=40.91%ii. For year 1994-95 =3360−25202520∗100=33.33%iii. For year 1996-97 =4320−31203120∗100=38.46%iv. For year 1997-98 =5040−43204320∗100=16.67%

First get the average of these 8 years.
which is,
1/8(2640+3720+2520+3360+3120+4320+5040+3120)
= 3480 million US $

Foreign exchange reserves in 1996-97 = 4320 million US $

Required Percentage =

(43203480∗100)%=125%

5. 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 is:

1. 3:5
2. 2:3

So required ratio is
3:5

Required Ratio =50403360
