A coffee seller has two types of coffee Brand A costing 5 bits per pound and Brand B costing 3 bits per pound he mixes two brands to get a 40 pound mixture he sold this at 6 bits per pound the sell?

Answer 1

he sold it 6 bits per pound.total pound=40.

then selling price=40*6=240.

it was given he made 33 1/2 percent profit,then the original price=180

since (x+x*33 1/2=240,then x=180)

then 1st equation is 5A+3B=180,

he mixes 2 brand to get 40 pound

so 2nd eq. A+B=40,after solving these equations ,we will get A=30................
