Show Answer

Correct Answer: (5)

Solution: (5)

Per cent of wallets of both types sold by stores $B$, $C$ and $E=(33.5+10+23.5) \%$ $=67 \%$

Their number $=\frac{4200 \times 67}{100}$ $=2814$

Number of tri-fold wallets sold by these stores $=(24+15+21) \%$ of 1800 $=\frac{1800 \times 60}{100}=1080$

$\therefore$ Number of two-fold wallets $=$ $2814-1080=1734$

$\therefore$ Required average $=\frac{1734}{3}$ $=578$
