let the sum of the age of 35 students be x
average=x/35=14
let the age of the teacher be y
x+y/36=15
x+y=15×36
x+y=540
x=14×35=490
therefore the age of the teacher=540-490=50years
average=x/35=14
let the age of the teacher be y
x+y/36=15
x+y=15×36
x+y=540
x=14×35=490
therefore the age of the teacher=540-490=50years
