80 person can write 140 test case in 42 days , if 30 person write 100 test case in how many days??

• According to question
  given m1=80,d1=42,w1=140
  m2=30,d2=x,w2=100
  m1*d1/w1=m2*d2/w2
  80*42/140=30*x/100
  x=80*42*100/140*30+>80
  No of days=>80

• 80 persons write 140 test case in 42 days.
  Thus, 80 persons will write 100 test case in (100*42)/140.
  As we know 30 person will take more time to write testcases as compared to 80.
  So, 30 persons will write 100 test cases in (100*42)/140*(80/30) =>80.
  Thus, 80 is right answer.

• 80
  TIME TAKEN BY ONE PERSON TO WRITE ONE CASE=80*42/140
  """"""""""""""30""""""""""""""""""100 "=(80*42*100)/(140*30)=80

• For first condition number of tests per person will be 140/80=7/4 in 42 days,similarly for second condition number of tests per person will be 100/30=10/3,so by cross multiplication, number of days for second condition will be =(10/3)(42)(4/7)=80.
