Answer 1

Answer:

54 & 29

Step-by-step explanation:

Father-f, Daughter- d

d-4 yrs ago daughter was 4,:

d-4 years ago: f-(d-4)=d => f=2d-4

79-f years later, daughter will be same age as father now:

79-f years later: d+(79-f)=f => f=(d+79)/2

Now lets compare the 2 equations we got:

2d-4=(d+79)/2

4d-8=d+79

3d=87

d=29

Then

f=2*29-4=54
