five years ago;
total age of 3 members= 3*27=81

let the sum of age of 3 members be x
given:average age before 5 years=27
x/3=27
x=27*3=81
let the age of new born be n
now average=25
(x+15+n)/4=25 (after 5 years age of each person will be increased by 5 so 5*3)
x+15+n=25*4
81+15+n=100
n=4
the age of child is 4
