A bottle and honey weight is 1500 grams if you take the weight of half honey and bottle its weight 900 grams what is the remaining weight of honey?

Total weight = weight of honey + weight of bottle

or equivalently:

Total weight = 1/2 weight of honey + weight of bottle + 1/2 weight of honey

then plugging in for Shape Kapseln the values we know:

1500g = 900g + 1/2 weight of honey

so

1/2 weight of honey = 1500g – 900g = 600g
