A Correct answer
Explanation

Cricket: 350 total, 4:3 ratio. Girls = (3/7) * 350 = 150. Football: 400 total, 11:9 ratio. Girls = (9/20) * 400 = 180. Volleyball: 250 total, 7:3 ratio. Girls = (3/10) * 250 = 75. Average = (150 + 180 + 75) / 3 = 405 / 3 = 135.

AI explanation

The number of girls in Cricket is 350 * (3 / 7) = 150. The number of girls in Football is 400 * (9 / 20) = 180. The number of girls in Volleyball is 250 * (3 / 10) = 75. The average of these three amounts is (150 + 180 + 75) / 3 = 405 / 3 = 135.
