    A 49 Correct Answer Incorrect Answer
    B 40 Correct Answer Incorrect Answer
    C 56 Correct Answer Incorrect Answer
    D 48 Correct Answer Incorrect Answer

    Solution

    We know that, Sum of angles of a triangle = 180o (x + 25) + (x + 59) + 10x = 180 Or, 12x + 84 = 180 Or, 12x = 96 So, 'x' = 8 So, required value = 7x = 7 X 8 = 56
