B Correct answer
Explanation

Original fare = 12100. Ratio 11:13 means 11 parts = 12100, so 1 part = 1100. Increase = 13 parts - 11 parts = 2 parts. Increase = 2 * 1100 = 2200.

AI explanation

Let the new flight fare be x, establishing the proportion 11 divided by 13 equals 12100 divided by x. Solving for x yields x equal to 12100 multiplied by 13 and divided by 11, which gives a new fare of 14300 rupees. The increase in fare is 14300 minus 12100, resulting in 2200 rupees.
