Answer 1

please mark it as brain list. if U understood....

Answer 2

$Let \: number \: boys \: in \:a \:school = b$

$Number \:of \:girls = b + 42$

$\blue{ Total \: number \:of \:students = 534 }$

$(given)$

$b + (b+42) = 534$

$\implies 2b + 42 = 534$

$\implies 2b = 534 - 42$

$\implies 2b = 492$

$\implies b = \frac{492}{2}$

$\implies b = 246$

Therefore.,

$\red{ Number \:of \:boys} \green { = 246}$

$\red{ Number \:of \: girls} \\= b + 42\\= 246+42\\\green{ = 288 }$
