a software company has 850 employees of whom 81% are software engineers and 19% are sales representatives to obtain a 25% sales representative proportion how many additional employees should be added to the sales staff?
a)212
b)68
c)161
d)53
d)51

• so total employees =850
  where they given 19% are sales rep so we need to obtain 25% sales rep so 25%-19%=6%
  so, 850*6/100=51
  51 additional employees should be added
  
  whether this is correct ???

• b) 68
  
  In existing 850 employees, software engineers=850*(81/100) & sales representative=850*(19/100)
  Let 'x' number of sales representative are added to make their proportion to 25%, then
  [850*(19/100) + x]/(850+x) = 25/100
  => [850*(19/100) + x]/(850+x) = 1/4
  Solving we get, x=68

• option b.) 68
  sol:
  {no. of 25% of employee / total employee }*100 = 25
  So,
  {(850*(19/100) + x) / (850+x) }*100 = 25
  on solving for x
  x = 68

• ans. 68
  let x be number of increased employee
  (19% of 850) + x = 25 % of (850 + x)

• b) 68 is right answer
• 5 years agoHelpfull: Yes(3) No(3)
• 81%=81/100*850=688(S/W Engineers)
  19%=19/100*850=162(Sales Representatives)
  25%=25/100*850=212
  212-162=51
  So, 51 more sales representatives are needed to make it 25%.

• 25/100*850=212.5
• 5 years agoHelpfull: Yes(1) No(2)
• ans should be 68(b)
  we know that,
  (850*81)/100=688.5;
  for making 25% sales 75% should be software engineer;
  i.e 688.5 represent 75% of total;
  let 'x' be the total no of employee,
  then (x*75)/100=688.5
  i.e. x=918;
  so additional 918-850=68 sales employee required.

• The ans is 51..
  
  
  19% of 850
  25% of 850
  Difference if 6%
  It becomes 51 more
