Calculation
City A: Boys : Girls = 3 : 2 → Total parts = 5
Boys = [3/5] × 1080 = 648
Girls = [2/5] × 1080 = 432
City B: Boys : Girls = 3 : 1 → Total parts = 4
Boys = [3/4] × 720 = 540
Girls = [1/4] × 720 = 180
Total Boys = 648 + 540 = 1188
Total Girls = 432 + 180 = 612
Difference = 1188 – 612 = 576
