A family of 6 is made up of a father a mother n 4 girls.
the average age of the family z 25 yrs .
the average age of the 4 girls z 15 yrs.
:
(i) wat z d total age of d 4 girls?
4(15) = 60
:
(ii) find the sum of the age of the father and mother
let p = average age of the parents
then
= 25
60 + 2p = 6(25)
2p = 150 - 60
2p = 90 is the sum of the parent's ages
;
(iii) is the father z 2 yrs olda dan d mother, wat z the age of the mother?
let m = the mother's age
then
(m+2) = the father's age
therefore
m + (m+2) = 90
2m = 90 - 2
2m = 88
m = 88/2
m = 44 yrs if the mother's age
