E., but I backsolved.

1/6(180)=30

30+10=40 handmade ornaments/2=20 handmade antique ornaments

20/180=1/9.

No of ornaments = X

Handmade : 1/6X +10

Handmade Antique : (1/6X+10)/2
1/9X
(1/6X +10)/2 = 1/9X
=>9/6x+90 = 2x
=>90 = 0.5x
x = 180

double set matrix is the best way to solve this.

x is the amount of ornaments.

so x/6+10 = total handmade.

(x/6+10)/2= total handmade and antique

x/9= total handmade and antique

x/6+10=2x/9 --> 10=4x/18-3x/18 --> x=180
