Correct Answer: 64.70%
Solution :
Total number =11200
The ratio of Dell to HP laptops sold by B = 7 : 6
Number of dell laptops sold by B = $\frac{7}{7+6}\times$ 26% of 11200
= $\frac{7}{13}\times\frac{26}{100}\times 11200$
= 1568
The ratio of Dell to HP laptops sold by E = 4 : 3
And the ratio of Dell to HP laptops sold by F = 3 : 1
And the number of HP laptops sold by E and F together =
= $\frac{3}{4+3}\times$14% of 11200 + $\frac{1}{3+1}\times$10% of 11200
= $\frac{3}{7}\times\frac{14}{100}\times 11200+\frac{1}{4}\times\frac{10}{100}\times 11200$
= 672 + 280 = 952
$\therefore$ Required percentage = $\frac{1568-952}{952}\times 100=64.70$%
Hence, the correct answer is 64.70%.
