Answer 1

Answer:

46 years

Step-by-step explanation:

(( A − 5 ) + ( B − 5 ) + ( C − 5 ) + ( D − 5 )) / 4 = 46

(A + B + C + D - 20) / 4 = 46

A + B + C + D - 20 = 46 x 4

A + B + C + D = 184 + 20 = 204

Now,

( A + B + C + D + E ) / 5 =  50

A + B + C + D + E = 50 x 5 = 250

E = 250 - 204 = 46 years

Hope it helps!
