A trade bought corn for sh 20 per kilogram and beans for sh 60 per kilogram. She mixed the corn and beans and sold the mixture at sh 48 per kilogram. If she made a 60% Profit, determine the ratio corn: beans per kilogram in the mixture.
cost: 20c+60b
revenue: 48(c+b)
so, 48(c+b)=8/5 (20c+60b)
240c+240b = 160c+480b
80c = 240b
c/b = 240/80 = 3
that is, c:b = 3:1
How did you got 8/5?
