Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A group of people contains men, women, and children. The number of men is twice the number of women, and the number of women is 3 times the number of children. If the number of children is 30, how many people does this group contain?

### Response:
 Idadi ya wanawake katika kundi ni 3 wanawake/mtoto * 30 watoto = <<3*30=90>>90 wanawake.
Idadi ya wanaume katika kundi ni 2 wanaume/mwanamke * 90 wanawake = <<2*90=180>>180 wanaume.
Jumla ya watu katika kundi ni 90 wanawake + 180 wanaume + 30 watoto = <<90+180+30=300>>300 watu.
