Answer 1

Step-by-step explanation:

example only

A man is 5 years older than his wife and the wife is now 4 as old as their son, who is 12 years old. How old was the man when his daughter was born?

Given that, man is 5 years older than his wife and wife is 4 as old as daughter.

Daughter is 12 years old.

Let the man's age be M, wife's age be W and daughter's age be D.

Thus according to given condition,

we have

M=W+5 ....

(1),

W=3D ....

(2)

and D=12 ....

(3)

Putting d=12 in equation

(2), we get

W=3D=3×12=60

Put W=60 in equation

(1), we get

M=W+5=60+5=65

So, man's age when his daughter was born will be 65−10=55 years.
