There are two bottles of orange juice with different sugar content. A weighs 150g, B weighs 200g. Now pour out the same amount of orange juice and exchange it into a bottle. At this time, the sugar content is equal. How many grams of orange juice are poured out?

Let the sugar content of a and B be a and B respectively; the poured orange juice is x [(150-x) a + BX] / (150-x + y) = [(200-x) B + ax] / (200-x + x) 4 [(150-x) a + BX] = 3 [(200-x) B + ax] 600a-4ax + 4bx = 600b-3bx + 3ax600a-600b = x (7a-7b) x = [600 (a-b)] / [7 (a-b)] x = 600 / 7, so the poured orange juice is 60

A bottle of orange powder is 450 grams. Each cup of orange juice needs 16 grams of orange powder and 10 grams of sugar. How many grams of sugar do you need to finish this bottle of orange powder?

Xiao Li drank a glass of orange juice, first drank 25% of the water, then drank 30% of the glass, then filled with water, then drank 45%, finally filled with water
How much water did Xiao Li drink?

A glass of water 1-25% = 75%, that is to say, now there is 75% orange juice. When he drinks 30%, he drinks 25% water and another 5% orange juice. 30% - 25% = 5% 75% - 5% = 70%. Now there is still 70% orange juice left. He fills it up again and drinks 45%, that is to say, he adds 30% water and 45% - 30% = 15% 70% - 15% = 55% water: 25% + 3
