    Question

    A basket contains x green apples, (x + 2) red apples and (x

    + 10) yellow apples. If probability of getting a red apple is 1/8 more than that of getting a green apple, then find the probability of getting a yellow apple.
    A 15/12 Correct Answer Incorrect Answer
    B 17/24 Correct Answer Incorrect Answer
    C 21/24 Correct Answer Incorrect Answer
    D 11/12 Correct Answer Incorrect Answer

    Solution

    ATQ,

    (x + 2 – x)/(3x + 12) = 1/8

    Or, 3x + 12 = 16

    Or, x = 4/3

    So, desired ratio = (4/3 + 10)/(16) = 34/48 = 17/24
