The total ages of A and B is 12 years more than the total ages of B and C. How many years younger is C younger than A?

• 12 years
  
  A+B= 12+B+C or A-12=C
  So C is 12 years younger than A

• a +b - (b+c)=12
  a-c=12
  C is 12 yrs younger than A.

• A+B=12+B+C
  C=A-12
  C is 12 years younger than A
• 8 years agoHelpfull: Yes(0) No(0)
• A+B=12+B+C
  A=12+C
  
  C IS 12 YEARS YOUNGER THAN A.

• suppose, age of A is x , age of B is y , age of C is z years.
  A+B total age = {B+C total age} +12
  x+y = y+z+12
  x-z = 12
  so, c is 12 years younger than A.
