    The average marks scored by him (excluding his highest and lowest marks) are 80 and lowest marks scored by him are 60. Find the highest marks scored by him.

    C 110 Correct Answer Incorrect Answer
    D 130 Correct Answer Incorrect Answer

    Solution

    Sum of marks scored by him in five subjects = 5 x 90 = 450 Sum of marks scored by him (excluding his highest and lowest marks) = 3 x 80 = 240 Therefore, sum of highest and lowest marks = 450 – 240 = 210 So, highest marks scored by him = 210 – 60 = 150
