Solution:

Total number of foreign exchange reserves (in million US

\$

) in the given years
= 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120 = 27,840
⇒ Average foreign exchange reserves (in million US

\$

) =

27,840/8=3480

Number of years in which the foreign exchange reserves are above the average reserves = 3 (92-93, 96-97, 97-98)
Number of years in which the foreign exchange reserves are below the average reserves = 5
⇒ Required ratio = 3 : 5
