Show Answer

Correct Answer: (3)

Solution: (3)

Number of linen shirts sold by stores $D$ and $E$

$= (\frac{84000 \times 12}{100} \times \frac{5}{8}) + (84000 \times \frac{28}{100} \times \frac{4}{7})$

$= 6300 + 13440 = 19740$

Number of cotton shirts sold by these stores

$= 84000 \times \frac{12}{100} \times \frac{3}{8} + 84000 \times \frac{28}{100} \times \frac{3}{7}$

$= 3780 + 10080 = 13860$

$∴$ Required difference $= \frac{1}{2} (19740 - 13860)$

$= \frac{5880}{2} = 2940$
