Question

Stores M and N sell only two types of hats: Fedora hats and Trilby hats. If the respective ratio of the total number of Fedora hats to the total number of Trilby hats sold by stores M and N together during March is 9:5, which is the total number of Fedora hats sold by stores M and N together during March?

• A. 990
• B. 900
• C. 720
• D. 630
• E. 810

Answer 1

The correct option is E 810

Let the total number of Fedora hats sold by stores M and N together during March be 9x and the total number of Trilby hats sold by stores M and N together during March be 5x. Total number of hats sold by M and N during March = 780 + 480 = 1260
$\therefore 9x+5x=1260$
$14x=1260,x=90$
Hence, the total number of Fedora hats sold by stores M and N together during March $=9x=9\times 90=810$.
