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

### Instruction:
Three schools organized a science fair competition and invited students from all the schools to develop ideas and present them before a panel of judges selected by all the schools competing in the science fair. There were 50 students from Know It All High School at the competition, 3/5 times as many students from Karen High as Know It All High School, and twice the combined number of students from the first two schools that came were from Novel Corona High School. Calculate the total number of students at the competition?

### Response:
 Ikiwa wanafunzi 50 walikuja kutoka Shule ya Upataji Wote, basi Karen High, ambayo ilikuwa na mara 3/5 ya idadi ya wanafunzi kama Shule ya Upataji Wote, ilikuwa na wanafunzi 3/5*50 = 30 katika mashindano.
Idadi jumla ya wanafunzi kutoka Shule ya Upataji Wote na Karen High ni 50+30 = <<50+30=80>>80 wanafunzi.
Ikiwa Novel Corona ilikuwa na mara mbili ya idadi ya wanafunzi kutoka Shule ya Upataji Wote na Karen High, basi ilikuwa na wanafunzi 2*80 = <<2*80=160>>160 katika mashindano.
Idadi jumla ya wanafunzi katika mashindano ni 160+80 = <<160+80=240>>240
