The aggregate marks of three students A,B,C is 180. What are the marks of each student?

1. B and C together obtain 85 marks.
2. A and C together obtain 70 marks.

• Given, A+B+C=180
  Cond 1) B+C=85
  then putting cond 1 into given we got, A=180-85=95
  Cond 2) A+C=70
  Putting A's value, C=70-95=-25
  Now putting A's & C's value we got, B= 180-95+25=110
  Answer, A=95, B=110, C= -25

• A+B+C=180----1
  B+C=85---2
  A+C=70---3
  adding 2 and 3 we get
  B+C+A+C=155
  ie A+B+2C=155---4
  
  subtracting 1 and 4
  A+B+C-A-B-2C=180-155
  =25

• b+c=85
  a+c=70
  a+b+c=180
  a+85=180
  a=95
  simirarly b=110 c=-25

• a+b+c=180
  b+c=85
  a+c=70
  here a=180-85=95
  b=180-70=110
  c=180-205=-25
