The number of kilometres that she drives on a Tuesday was 12.5% less than the number of kilometres that she drives on the day before.On the other hand, the number of kilometres that she drives on Wednesday was 20% more than the number of kilometres that she drives on Tuesday.

- A.
324 km
- B.
320 km
- C.
318 km
- D.
315 km
Answer: Option B
Explanation :
Let the distance covered on Monday be 'x' kms.
∴ Distance travelled on Tuesday is 12.5% less than that on Monday = x × (1 - 1/8) = 7x/8
∴ Distance travelled on Wednesday is 20% more than that on Tuesday = 7x/8 × (1 + 1/5) = 21x/20
Distance travelled on Wednesday is 336 kms.
⇒ 21x/20 = 336
∴ x = 336 × 20/21 = 320 kms.
Hence, option (b).
