Step-by-step explanation:
Let the age of oldest neighbour be x
let the age of youngest neighbour be x-30
According to question,
x+28+x-30 = 80
or, 2x +28-30=80
or,2x+28=80+30
or, 2x=110-28
or, 2x=82
or, x=82/2 = 41
Therefore, The age of oldest neighbour is 41 years
& The age of youngest neighbour= x-30 = 41-30 = 11 years!
