Question
A = (5/2) Γ B and C = (1/10) Γ A. If (A + B + C) =
255, then determine the value of (7C β B).Solution
ATQ; A = 10C And, A = (5/2) Γ B So, 10C = (5/2) Γ B Or, 4C = B Since, A + B + C = 255 So, 10C + 4C + C = 255 Or, 15C = 255 Or, C = 17 A = 17 Γ 10 = 170 And, B = 4 Γ 17 = 68 Required value = 7 Γ 17 β 68 = 51
