If the imports in 1998 was Rs. 250 crores and the total exports in the years 1998 and 1999 together was Rs. 500 crores, then the imports in 1999 was ?
The ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.
Let the exports in the year 1998 = Rs. xcrores.
Then, the exports in the year 1999 = Rs. (500 - x) crores.
∴ 1.25 = 250x ⇒ x = 2501.25 = 200 [Using ratio from 1998]
Thus, the exports in the year 1999 = Rs. (500 - 200) crores = Rs. 300 crores.
Let the imports in the year 1999 = Rs. ycrores.
Then, 1.40 = y300
y = (300 × 1.40) = 420.
∴ Imports in the year 1999 = Rs. 420 crores
