Question

What is the ratio of the number of novels (romantic and horror) sold by store E to the total number of horror novels sold by stores C and F together?

• A. 35 : 32
• B. 45 : 32
• C. 35 : 24
• D. 35 : 26
• E. 45 : 34

Answer 1

The correct option is D 35 : 26

Total number of novels sold by stores E
$=\frac{10\times 63000}{100}=6300$
Total number of horror novels sold by
store $C=\frac{63000\times 20}{100}-\frac{36000\times 24}{100}=12600-8640=3960$
And total number of horror novels sold by
store $F=\frac{6300\times 8}{100}-\frac{36000\times 12}{100}=5040-4320=720\therefore Requiredratio=6300:3960+720=6300:4680=630:468=35:26$
