The average marks scored by him (excluding his highest and lowest marks) are 56 and lowest marks scored by him are 40. Find the highest marks scored by him.Solution
Sum of marks scored by him in five subjects = 5 x 72 = 360 Sum of marks scored by him (excluding his highest and lowest marks) = 3 x 56 = 168 Therefore, sum of highest and lowest marks = 360 – 168 = 192 So, highest marks scored by him = 192 – 40 = 152
