The total amount of juice in a large bottle is 20*3/5= 12 (divide the large and small drinks into 5 parts). A large bottle of beverage is 12/ 12= 1.

If the number of two angles and one element is equal to the number of six angles, let the angle x 5 of the six angles be 40-x 0.6x+0.5(40-x)=23.

X=30, so the number of 2-angle 1 piece is x/2 = 15, and the 5-angle is 10.
