Answer & Explanation

**Explanation**

Required Ratio

= 5040/3360 = **1.5**

**Explanation:**

Foreign exchange reserve in 1997-98 = 5040 million US $

Foreign exchange reserve in 1993-94 = 2520 million US $

Increase = 5040 – 2520 = 2520 million US $

Percentage Increase =[(2520)/(2520)] X 100 ** ****= 100%**

**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:

- For year 1992-93 =[(3720−2640)/(2640)]∗100=
**40.91%** - For year 1994-95 =[(3360−25200)]/(2520)∗100=
**33.33%**

**iii.** For year 1996-97 =[(4320−3120)/(3120)]∗100 =**38.46 %**

**Iv**. For year 1997-98 =([5040−4320)/(4320)]∗100=**16.67****%**

**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 = [(4320/3480)]∗100)%=**125%**

**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’ was above the average and for rest of five years it was below the average

So required ratio is

**3:5**
