B Correct answer
Explanation

Total commuters = 10 * 1500 = 15000. New average with 8 trains = 15000 / 8 = 1875. Increase = 1875 - 1500 = 375.

AI explanation

The total number of commuters is found by multiplying the number of trains by the average commuters per train, giving 10 times 1500 which is 15000. When the trains are reduced to 8, the new average becomes 15000 divided by 8, which equals 1875. The average increase is the difference between the new average and the old average, so 1875 minus 1500 equals 375.
