Answer 1

let Ajay's age be x years
Reena's age = x + 6
ACC to question
x + x+ 6 = 28
2x = 28 - 6
x = 22/2
x = 11
Ajay's age = 11 years
Reena's age = 11 + 6 = 17 years
plz mark me as brainliest

Answer 2

$\mathbb{ Let \: \: the \: \: present \: \: age \: \: of \: \: her \: \: brother \: \: Ajay \: \: be \: \: x \: \: years \: } \\ \\ \mathbf { If \: \: Present \: \: of \: \: her \: \: brother \: \: is \: \: x \: \: years, so \: \: her \: \: present \: \: age \: \: will \: \: be ( x + 6 ) years \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [ according \: to \: the \: question ] } \\ \\ \\ \\ \\ \mathbf{ Given \: \: in \: \: the \: \: question,} Sum \: \: of \: \: their \: \: ages = 28 \: \: years$




Hence,


Present age of her brother Ajay + Reena's present age = 28 years


=> x + ( x + 6 ) = 28

=> x + x + 6 = 28

=> 2x = 28 - 6

=> 2x = 22

$=> x = \frac{22}{2} \\ \\ \\ \mathbf{ => \: \: x = 11} \\ \\ \\ \\ \\ \bold{Hence, \: \: Present \: \: age \: \: of \: \: her \: \: brother \: \: Ajay = x = 11 \: \: years} \\ \\ \bold{ Present \: \: age \: \: of \: \: reena = ( x + 6 )= ( 11 + 6 ) = 17 years}$
