Answer:
E=80 years
Step-by-step explanation:
the average age of A,B &C was 50 year
(A+B+C)/3=50
A+B+C=50*3
A+B+C=150
if five years ago the age of D is 75 year
Present age of D is 75-5=70
the present average age of A,B,C,D &E is 60 year
(A+B+C+D+E)/5=60
A+B+C+D+E=60*5
A+B+C+D+E=300
we know D and A+B+C values
150+70+E=300
E=80
