please mark me as brainliest

Answer 2

average of 6 students = 53

student 1 = 2+ student 2

Last 4 students average = 49

x-53/4 = 2/4

x-53 =2

x =55

average of 2 students =55

let the score of student 1 =x

then

x+ (x+2) /2 = 55

2x+2 = 110

x+1 = 55

x =54

student 1 score =54

student 2 score =56
