Correct Answer: (1)

Solution: (1)

$\because 30 \%$ of all male customers $=48$

$\therefore \quad$ All male customers $=\frac{48}{30} \times 100=160$

$\therefore \quad$ Number of female customers $=\frac{9}{4} \times 160=360$

For male customers :

Only macaroons $\Rightarrow \frac{160}{5}=32$

Only cupcakes $\Rightarrow \frac{3}{16} \times 160=30$

Only brownies $\Rightarrow 48$

All three cakes $\Rightarrow 8$

Only (macaroon and cupcakes + cupcakes and brownies + brownies and macroons) $=160-118=42$

$\Rightarrow a+a+a-6=42$

$\Rightarrow 3 a=42+6=48$

$\Rightarrow a=\frac{48}{3}=16$

$\therefore$ Only macaroons and cupcakes $\Rightarrow 16$

Only cupcakes and brownies $\Rightarrow 16$

Only brownies and macaroons $\Rightarrow 10$

For female customers :

Only macaroons $\Rightarrow \frac{1}{8} \times 360=45$

Only brownies $\Rightarrow \frac{3}{8} \times 360=135$

Only macaroons and cupcakes $\Rightarrow \frac{360}{10}=36$

Only cupcakes and brownies $\Rightarrow \frac{360}{20}=18$

Only cupcakes $\Rightarrow 2 \times 45=90$

Only macaroons and brownies $\Rightarrow 16$

All three cakes $=360-340=20$

Males who buy macaroons $=32+16+10+8=66$

$\therefore \quad$ Number of macaroons sold $=(22 \times 4+44 \times 2)$ $=88+88=176$
