Their is an answer to this question and i must say it's not easy. designed for the experianced, those who love mathematics.

I guess a lemon weighs 37.5 grams. EDIT: I guess I'm not good at guessing. Next time I will do the math.

a lemon weighs or maybe 29/27 kilos?? If that's not right I give up...

An orange is worth .25 kilos A grapefruit is worth .4 kilos And the lemon is .6 kilos i did it!!!

I know I'm late on this so I don't expect any points, but I like puzzles so I did it for fun, and since nobody has actually given their method, I thought I would write it out in full so people can see how to solve these things. Using g for grapefruits, o for oranges and m for lemons (since the 'l' looks too much like a one), we are told  1) 8g + 7o + 3m = 3o + 6g + 6m 2) g = 2m/3 3) 12o = 3 Straightaway we can work out o  divide both sides of equation 3 by 12 and we get o = 3/12, or 1/4kg. Then if we substitute this value into equation 1, it becomes  4) 8g + 3m + 7/4 = 6g + 6m + 3/4 Since we also know that 2) g = 2m/3, we can substitute this into equation 4 as well, giving  5) 8(2m/3) + 3m + 7/4 = 6(2m/3) + 6m + 3/4, which simplifies to 16m/3 + 3m + 7/4 = 12m/3 + 6m + 3/4 Gathering all the m terms on one side of the equation and all the numeric terms on the other gives us  6) 1 = 5m/3, or 3 = 5m, so m = 3/5kg And if g = 2m/3 as equation 2 says, then g = 2/3 * 3/5 = 2/5kg. So that is how we reach the answers of oranges = 1/4kg (250 grams), lemons = 3/5kg (600 grams) and grapefruits = 2/5kg (400 grams).

8G + 7O + 3L = 3O + 6G + 6L G = 2/3L 12O = 3 Kilo O = 3/12 Kilo or 0.25 kilo So 8G + 7(0.25) + 3L = 3(0.25) + 6G + 6L Then 8(2/3L) + 1.75 + 3L = 0.75 + 6(2/3L) + 6L Therefore 1 = (4L + 6L)  (5,1/3L + 3L) And in conclusion L = 1,2/3 Kilo Were have i gone wrong?

Now that that problem is solved let's mix it up with some ice and have a little citrus punch! Its add your own booze. I'll make cookies.
