Answer 2

Answer:

Given That :-

• Person's present age is 2/5 of his mother.

• Person'a age after 8 years will be one half of his mother's age.

To find :-

• Present age of mother.

$\tt\huge{Solution:}$

=> Let the mother's present age be x years.

Then, the person's present age = (2/5 x) years.

=> (2/5 x + 8/2) = 1 (x + 8)

 

=> 2(2x + 40) = 5(x + 8) 

$\boxed{x = 40}$
