D Correct answer
Explanation

The original fare corresponds to 5 parts of the ratio, which is given as Rs. 625, meaning each part is worth Rs. 125. The increase in fare is the difference between the new ratio and the old ratio, which is 2 parts (7 minus 5). Multiplying 2 parts by Rs. 125 gives an increase of Rs. 250.

AI explanation

To find the new fare, apply the proportion 5 divided by 7 equals 625 divided by x. Solving for x gives a new fare of Rs. 875. The increase in the fare is the difference between the new fare and the original fare, which is 875 minus 625, resulting in Rs. 250.
