    A 155 Correct Answer Incorrect Answer
    B 168 Correct Answer Incorrect Answer
    C 150 Correct Answer Incorrect Answer
    D 152 Correct Answer Incorrect Answer

    Solution

    The logic followed here is: 3 rd number: {(2 X 1 st number) + (3 X 2 nd number) }

    68 # 34 = 238= {(2 X 68) + (3 X 34) } = {136 + 102} = 238

    39 # 204 = 243= {(2 X 39) + (3 X 42) } = {78 + 126} = 204

    45 # 20 = ? = {(2 X 45) + (3 X 20) } = {90 + 60} = 150.
