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

### Instruction:
There were students from three different schools taking part in a debate organized by the town's mayor on a stage. The first school had twice as many students as the second school, and the second school had 40 more students than the third school. If the third school had 200 students, and after the debate was over, every student shook the mayor's hand, calculate the total number of students who shook the mayor's hand on the stage.

### Response:
 Ikiwa shule ya tatu ilikuwa na wanafunzi 200, na shule ya pili ilikuwa na wanafunzi 40 zaidi ya shule ya tatu, shule ya pili ilikuwa na wanafunzi 200+40 = <<200+40=240>>240.
Shule ya tatu na ya pili ilikuwa na jumla ya wanafunzi 240+200 = <<240+200=440>>440 kwenye jukwaa wanaoshiriki mdahalo.
Kwa kuwa shule ya kwanza ilikuwa na wanafunzi mara mbili ya shule ya pili, na shule ya pili ilikuwa na wanafunzi 240, shule ya kwanza ilikuwa na wanafunzi 240*2= <<240*2=480>>480 kwenye jukwaa wanaoshiriki mdahalo.
Ikiwa baada ya mdahalo kukamilika, kila mwanafunzi kwenye jukwaa alishikana mkono na meya, idadi ya wanafunzi walioshikana mkono na meya ni 480+440 = <<480+440=920>>920.
