Direction: Study the following bar-diagram carefully and answer the questions. The bar graph given below shows the foreign exchange reserves of a country (in million US $) from 1991-1992 to 1998 - 1999.
-
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 reserves is
-
- 2 : 6
- 3 : 4
- 3 : 5
- 4 : 4
Correct Option: C
On the basis of given graph in question ,
Sum of foreign exchange reserve = 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120
Number of years = 8
| Average foreign exchange reserve = | million dollar | 8 |
| Average foreign exchange reserve = | = 3480 million dollar | 8 |
Number of years, in which the foreign exchange reserves above average value = 3
Number of years, in which the foreign exchange reserves below average value = 5
Required ratio = Number of years, in which the foreign exchange reserves above average value : Number of years, in which the foreign exchange reserves below average value
∴ Required ratio = 3 : 5
