(both a and b with all the step by step write down)

Answer 1

$Total \:number \: of \: cards (x) = 300$

$Number \:of \:cards \:sold = \frac{3}{4} \:of \:x \\= \frac{3}{4} \times 300 \\= 225$

$Remaining \:cards = x - 225 \\= 300 - 225 \\= 75$

$Number \:of \:cards \:gave \:to \:neighbor \\= \frac{1}{3} \: of \: 75 \\= \frac{1}{3} \times 75 \\= 25$

$Number \: of \: cards \:left = 75 - 25 = 50$

Therefore.,

$\red{Number \: of \: cards \:left} \green { =50}$
