$\huge\bold{\gray{\sf{Answer:}}}$

Explanation:

Given:

Teena is 3 years younger than his brother and the sum of their ages is 32 years.

To Find :

Their present ages

ㅤㅤㅤㅤㅤㅤㅤㅤ

ㅤㅤㅤㅤㅤㅤㅤㅤㅤ

Let the teena's brother age be 'x'

Teena 's age then ='x-3'(because she is 3 years younger than his brother)

Now according to the question

Their sum of their ages is 32

$= > x + x - 3 = 32$

$= > 2x - 3 = 32$

$= > 2x = 35$

$= > x = \frac{35}{2} = 17.5$

Therefore ,Teena 's brother present age is 17.5 years

Now ,teena's present age is x-3=17.5-3=14.5 years

$\bold{\red{\underline{Check :-}}}$

sum of their ages :- 17.5

ㅤㅤㅤㅤㅤㅤㅤㅤㅤ. 14.5

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ______

ㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ 32.0
