Before solving this, put a clever eye on the chart, just calculate for those years which are actually having increase if we compare to previous year.
These years are 199293, 199495, 199697, 199798
So lets calculate the percentage increase of these years compared to previous years :
\begin{aligned}
\text{i. For year 199293 =}\frac{37202640}{2640}*100 \\
= 40.91\% \\
\text{ii. For year 199495 =}\frac{33602520}{2520}*100 \\
= 33.33\% \\
\text{iii. For year 199697 =}\frac{43203120}{3120}*100 \\
= 38.46\% \\
\text{iv. For year 199798 =}\frac{50404320}{4320}*100 \\
= 16.67\% \\
\end{aligned}

 80%
 100%

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 199697 = 4320 million US $
Required Percentage =
\begin{aligned}
\left( \frac{4320}{3480}*100\right)\%
= 125\%
\end{aligned} 
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:
