Question
A = (4/3) × B and C = (1/8) × A. If (A + B + C) = 210,
then determine the value of (9C – B).Solution
ATQ; A = 8C And, A = (4/3) × B So, 8C = (4/3) × B Or, 6C = B Since, A + B + C = 210 So, 8C + 6C + C = 210 Or, 15C = 210 Or, C = 14 A = 14 × 8 = 112 And, B = 6 × 14 = 84 Required value = 9 × 14 – 84 = 42
