Answer:
| City | Population | Adults |
| U | 20 x 28000 = 560000 | 55 x 5600 = 308000 |
| V | 19 x 28000 = 532000 | 60 x 5320 = 319200 |
| W | 17 x 28000 = 476000 | 68 x 4760 = 323680 |
| X | 21 x 28000 = 588000 | 66 x 5880 = 388080 |
| Y | 9 x 28000 = 252000 | 72 x 2520 = 181440 |
| Z | 14 x 28000 = 392000 | 70 x 3920 = 274400 |
1. 2; Total number of adults in city Y = 181440
Total number of males in city X
= x 588000 = 252000
∴ Required percentage = x 100 = 72%
2. 3; Required difference = x 532000= 84000
3. 5; Data not sufficient
4. 5; Number of male population in city Z
= 392000 x = 2,24,000
5. 2; Number of persons in city W who are not adult
= x 476000 = 152320
4. 5; Number of male population in city Z
= 392000 x = 2,24,000
5. 2; Number of persons in city W who are not adult
= x 476000 = 152320
