Question

The average marks of ten students is 60.If the highest marks is excluded the average is 59.Find the highest marks.

Answer 1

Answer:

Step-by-step explanation:

total marks obtained by ten students = 60×10 =600.

let the highest mark was x.

so marks obtained by 9 students =600-x.

average marks of 9 students =marks obtained by 9 students /9.

59 =( 600-x)/9

59×9 =600-x

600-x =531

x =600- 531

x =69.
