According to given data,
Total number of persons = 2880000
Number of persons in city A in degrees = 600
Also, the number of adults : number of children = 3 : 1
Total number of children in city A =2880000 × 60/360 × 14 = 120000
Number of persons in city B in degrees = 750
Also, the number of adults : number of children = 2 : 1
Therefore, the total number of children in city B = 2880000 × 75/360 x 13 = 200000
Similarly,
Total number of children in city C = 2880000 × 55/360 × 311 = 120000
Total number of children in city D = 2880000 × 70/360 × 27 = 160000
Total number of children in city E = 2880000 × 65/360 × 313 = 120000
Total number of children in city F = 2880000 × 35/360 × 15 = 56000
Total number of children in all cities together = 120000 + 200000 + 120000 + 160000 + 120000 + 56000 = 776000
Total number of adults in all cities together =2880000 − 776000 = 2104000
