Average marks scored by Vineet in five subjects are 70.
The average marks scored by him (excluding his highest and lowest marks) are 50 and lowest marks scored by him are 45. Find the highest marks scored by him.Solution
Sum of marks scored by him in five subjects = 5 x 70 = 350 Sum of marks scored by him (excluding his highest and lowest marks) = 3 x 50 = 150 Therefore, sum of highest and lowest marks = 350 – 150 = 200 So, highest marks scored by him = 200 – 45 = 155
