(2) weight of sugar ÷ weight of sugar water × 100%= sugar content (concentration of sugar water)
(3) Sugar content of 35% means that sugar accounts for 35 parts and sugar water accounts for100;
(4) Late sugar: 35+5 = 40 (g)
(5) Late sugar water: 100+5+20 = 125 (g)
(6) At this time, the concentration of sugar water: 40125×100% = 32%.
