Question

The total number of luxury watches sold by stores C and H together is what percent less than the total number of watches (sports watches & luxury watches) sold by stores F and H together?

• A. $26\frac{5}{6}$
• B. $27\frac{3}{7}$
• C. $31\frac{3}{5}$
• D. $28\frac{4}{7}$
• E. $26\frac{5}{9}$

Answer 1

The correct option is D $28\frac{4}{7}$

Total number of luxury watches in store C and H together
$=\frac{(14+9)}{100}\times 56000-\frac{19\times 32000}{100}=23\times 560-19\times 320=1280-6080=6800$
Total number of watches in store F and H together $=\frac{17\times 56000}{100}=9520$
$\therefore$ Required percentage
$=\frac{9520-6800}{9520}\times 100=\frac{2720}{9520}\times 100=\frac{27200}{952}=28\frac{544}{982}=28\frac{4}{7}\%$
