Answer 1

Answer:

Step-by-step explanation:

let the age of husband wife and child be h, w, and c

five years ago, the age was = h-5, w-5 and c-5

and average = sum of observation/number of observation

given that

(h-5+w-5+c-5)/3 = 26

(h+w+c-15) = 78

h+w+c = 93 -------1

also given that

(w-6+c-6) / 2 = 24

w+c-12 = 48

w+c = 60

Putting this in equation 1

we get

h+60 = 93

or h=33.
