Answer:
36 years.
Step-by-step explanation:
let their ages be x.
5x + 4x = 81 (sum of their ages is 81)
9x = 81
x = 81/9
x = 9
The age of man(5x) = 5 × 9 => 45 years.
And age of wife(4x) = 4 × 9 => 36 years.
Therefore the age of younger person ,that is the wife is 36 years.
Hope it helps you...

Answer:
The woman is younger person and her age is 36
Step-by-step explanation:
Man age+ Woman age= 81
Ratio= 5:4
Then,
5:4= 5/4
We can write as 5x/4x
⇒5x+4x=81
⇒9x= 81
⇒x=81/9
⇒x=9
Therefore,
The age of man =5×9=45
The age of woman=4×9=36.
The younger person is woman and the age of woman is →36 years←
