Let sugar be x and water be y, Then, y:x = 8:3 or, y/x = 8/3 or, 3y = 8x or, y = 8x/3 ............................. (1) Again, y:(x+2) = 2:1 or, y/(x+2) = 2/1 or, y = 2x + 4 Now, 8x/3 = 2x + 4 or, 8x = 6x + 12 or, 8x - 6x = 12 or, 2x = 12 or, x = 6 Thus, originaly, there were 6 kg of sugar.Related questions
