If the imports in 1998 was ₹ 250 crores and the total exports in the years 1998 and 1999 together was ₹ 500 crores, then the imports in 1999 was ?
- A ₹ 250 crores
- B ₹ 300 crores
- C ₹ 357 crores
- D ₹ 420 crores Correct
- E None of these
Correct Answer: Option D
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 = ₹ x crores.
Then, the exports in the year 1999 = ₹ (500 - x) crores.
 1.25 = |
250 |  x = |
250 | = 200 |
| x | 1.25 |
[Using ratio for 1998]
Thus, the exports in the year 1999 = ₹ (500 - 200) crores = ₹ 300 crores.
Let the imports in the year 1999 = ₹ y crores.
| Then, 1.40 = | y | y = (300 x 1.40) = 420. |
| 300 |
Imports in the year 1999 = ₹ 420 crores.
