\end{aligned}

• 3. FOr which year, the percent increase of foreign exchange reserves over the previous year is the highest ?

1. 1994-95
2. 1995-96
3. 1998-99
4. 1992-93
Answer And Explanation

Answer: Option D

Explanation:

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 1992-93, 1994-95, 1996-97, 1997-98

So lets calculate the percentage increase of these years compared to previous years :
\begin{aligned}
\text{i. For year 1992-93 =}\frac{3720-2640}{2640}*100 \\
= 40.91\% \\
\text{ii. For year 1994-95 =}\frac{3360-2520}{2520}*100 \\
= 33.33\% \\
\text{iii. For year 1996-97 =}\frac{4320-3120}{3120}*100 \\
= 38.46\% \\
\text{iv. For year 1997-98 =}\frac{5040-4320}{4320}*100 \\
= 16.67\% \\
\end{aligned}

• 4. The foreign exchange reserves in 1996-97 were approximately what percent of the average foreign exchange reserves over the period under review ?

1. 80%
2. 100%
3. 125%
4. 130%
Answer And Explanation

Answer: Option C

Explanation:

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 =
\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:

1. 3:5
2. 2:3
3. 4:7
4. 3:7
Answer And Explanation

Answer: Option A

Explanation:

Average foreign exchange reserves over the given period is = 3480 million US $The country had reserves above 3480 million US$ during the years 1992-93, 1996-97 and 1997-98. So three years is was above the average and for rest of five years it was below the average
So required ratio is
3:5
