Three factories Buka, Sakono and Rama produce sugar in one hundred kilogram bags daily. Buka produces three times as much as Rama. Sakono produced two times as much as Rama. If Sakono produces 500 bags, how many tones altogether do three factories produce daily?

B=3R

S=2R

so, 2R=500
find R, and the total is 6R*100kg

convert that to "tones"
