1050 students take any one of the following subjects as their specialization - Physics, Chemistry and Biology. If the number of students opting for Biology is 1.5 times the number of students opting for Physics and Chemistry each, then how many students opt for Chemistry

• let chem be x = phy be x
  x+x+1.5x=1050
  x=300ANS

• let phy, chem and bio students be p,c,b respectively.
  p+c+b=1050
  b=1.5p=1.5c. so, p=c
  p+p+1.5p=1050
  p=300=c. Hence, chem=300 ans

• 1.5x+x+x=1050
  x=300
  so ans=300

• 300
  3050/3.5=300

• p+C+B=1050
  p=1.5*c+1.5*B
  let opting for C=x and B=x
  then P=3x
  3x+1.5x+1.5x=1050
  6x=1050
  x=1050/6
  x=175
