Correct Answer: (3)
Solution: (3) Number of linen shirts sold by stores $D$ and $E$
$=\left(\frac{84000 \times 12}{100} \times \frac{5}{8}\right)+$
$\left(84000 \times \frac{28}{100} \times \frac{4}{7}\right)$
$=6300+13440=19740$
Number of cotton shirts sold by these stores
$=84000 \times \frac{12}{100} \times \frac{3}{8}$
$+84000 \times \frac{28}{100} \times \frac{3}{7}$
$=3780+10080=13860$
$\therefore$ Required difference
$=\frac{1}{2}(19740-13860)$
$=\frac{5880}{2}=2940$
