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

### Instruction:
 Paddy's Confidential ina makopo 600 ya supu inayohitajika kuwalisha watu 40. Makopo mangapi yatahitajika kuwalisha watu 30% wachache?


### Response:
 Idadi ya makopo yanayohitajika kuwalisha watu 40 ilikuwa 600.
Ikiwa idadi ya watu imepunguzwa kwa 30%, basi idadi ya makopo yanayohitajika itakuwa 600*(100%-30%)/100% = <<600*(100%-30%)/100=420>>420.
