A and B are shooters and having their exam. A and B fall short of 10 and 2 shots respectively to the qualifying mark. If each of them fired atleast one shot and even by adding their total score together, they fall short of the qualifying mark, what is the qualifying mark?

• Qualifying mark = 11
  
  If a & b are scores of A and B respectively and Q is qualifying score, then
  Q = a+10, a = Q-10
  Q=b+2, b= Q-2
  Q = a+b+1 = Q-10+Q-2+1= 2Q-11
  Q=11
  a=1
  b=9

• qualifying mark=10
  if a & b are scores of A and B respectively and Q is qualifying score,
  Q=a+10,a=Q-10
  Q=b+2,b=Q-2
  Q=a+b+1+1=Q-10+Q-2+1+1
  Q=10
