B Correct answer
Explanation

The ratio 9:11 means the original fare is 9 parts and the new is 11 parts. 9 parts = 675, so 1 part = 75. The increase is 2 parts (11 - 9), which is 2 * 75 = 150.

AI explanation

The original fare represents 9 parts of the ratio and is equal to Rs. 675. The new fare represents 11 parts, making the increased fare equal to 2 parts. Since one part equals 675 / 9 = Rs. 75, the increase in the fare is 2 * 75 = Rs. 150.
