Answer 1

Answer:

C) 45

Step-by-step explanation:

Description for Correct answer:

(A−5)+(B−5)+(C−5)+(D−5)4 = 45

A+B+C+D−204 = 45

A+B+C+D = 180+20 = 200

Now A+B+C+D+E5 = 49

A+B+C+D+E = 245

A+B+C+D+E = 245 - 200 = 45

Five years ago, the average age of A, B, C and D was 45 years with E joining them now, the average age of all the five is 49 years.
