    Question

    A = (7/3) × B and C = (1/14) × A. If (A + B + C) =

    360, then determine the value of (10C – B).
    A 480/7 Correct Answer Incorrect Answer
    B 318/5 Correct Answer Incorrect Answer
    C 451/7 Correct Answer Incorrect Answer
    D 525/7 Correct Answer Incorrect Answer

    Solution

    ATQ; A = 14C And, A = (7/3) × B So, 14C = (7/3) × B Or, 6C = B Since, A + B + C = 360 So, 14C + 6C + C = 360 Or, 21C = 360 Or, C = 120/7 A = (120/7) × 14 = 240 And, B = 6 × (120/7) = 720/7 Required value = 10 × (120/7) – (720/7) = 480/7
