The average marks scored by him (excluding his highest and lowest marks) are 65 and lowest marks scored by him are 55. Find the highest marks scored by him.Solution
Sum of marks scored by him in five subjects = 5 x 80 = 400 Sum of marks scored by him (excluding his highest and lowest marks) = 3 x 65 = 195 Therefore, sum of highest and lowest marks = 400 – 195 = 205 So, highest marks scored by him = 205 – 55 = 150
