Answer:
1. The total number of participants = 60 + 84 + 180 = 284 (ans)
2. LCM of 60, 84, and 108 will be = 3780
12 × 5 × 5 × 3 = 3780(ans)
3. HCF of 60, 84 and 180 will be = 12
2 × 2 × 3 = 12(ans)
4. The no. of rooms required for participants is already found out by taking HCF of children and there are 21 required for participants .
5 + 7 + 9 = 21 (ans)
5. No. of rooms required for participants are 21 and as mentioned above one more room was required for officials so 21 + 1 = 22 (ans)
