      B 8,500 Correct Answer Incorrect Answer
      C 3,750 Correct Answer Incorrect Answer
      D 2,200 Correct Answer Incorrect Answer

      Solution

      ATQ,

      Ratio of profit share of A and B respectively:

      = [(P + 700) × 12] : [2P × 7]

      = (12P + 8400) : 14P

      = (6P + 4200) : 7P (dividing by 2)

      ATQ;

      (6P + 4200) : 7P = 8 : 7

      Or, 6P + 4200 = 8P

      Or, 2P = 4200

      Or, P = 2100

      Required value = 2100 − 100 = 2000
