Answer» B - A = A - C (B + C) = 2A Now given that, (B + C) = 50 So, 50 = 2A and therefore A = 25. QUESTION is (B - A) = ? Here we know the value(AGE) of A (25), but we don't know the age of B. Therefore, (B-A) cannot be DETERMINED. B - A = A - C (B + C) = 2A Now given that, (B + C) = 50 So, 50 = 2A and therefore A = 25. Question is (B - A) = ?
