Question

    ‘x’ varies directly as ‘y’. If at x = 24 the

    value of ‘y’ is 25% more than ‘x’, then find the value of ‘x’ when ‘y’ = 55.
    A 56 Correct Answer Incorrect Answer
    B 44 Correct Answer Incorrect Answer
    C 40 Correct Answer Incorrect Answer
    D 36 Correct Answer Incorrect Answer

    Solution

    ATQ; X = k × y (Where ‘k’ is proportionality constant) ATQ; 24 = k × (1.25 × 24) Or, k = (4/5) So, required value = (4/5) × 55 = 44
