    C 140 Correct Answer Incorrect Answer
    D 130 Correct Answer Incorrect Answer

    Solution

    Sum of marks scored by him in five subjects = 5 x 75 = 375 Sum of marks scored by him (excluding his highest and lowest marks) = 3 x 60 = 180 Therefore, sum of highest and lowest marks = 375 – 180 = 195 So, highest marks scored by him = 195 – 55 = 140
