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 $=\frac{1734}{3}$
$=578$
