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? Let's think step by step and output the final answer after "####".

If 50 students came from Know It All High School, then Karen High, which had 3/5 times as many students as Know It All High School, had 3/5*50 = 30 students at the fair.
The total number of students from Know It All and Karen high schools is 50+30 = <<50+30=80>>80 students.
If Novel Corona had twice the combined number of students from Know It All and Karen high schools, then it had 2*80 = <<2*80=160>>160 students at the competition.
The total number of students at the competition is 80+160 = <<80+160=240>>240
