    Question

    If x : y : z = 5 : 6 : 8, and (3x + 4z) = 188, then

    find the value of y.
    A 18 Correct Answer Incorrect Answer
    B 20 Correct Answer Incorrect Answer
    C 24 Correct Answer Incorrect Answer
    D 30 Correct Answer Incorrect Answer

    Solution

    Let x = ‘5a’ So, y = 5a × (6/5) = ‘6a’ And z = 5a × (8/5) = ‘8a’ ATQ; 5a × 3 + 8a × 4 = 188 Or, 15a + 32a = 188 So, 47a = 188 So, a = 4 So, required value = 6a = 24
