The question seems to have some errors.
Correct question may be:
Gun-powder contains 75% nitre , 15% charcoal and the rest of it is sulphur. find the total weight of charcoal and sulphur in 3 kg of gun -powder.
Solution:
Weight of charcoal=(15/100)×3 kg
=45/100 kg
=0.45 kg =450 g
Percentage of sulphur=100-(75+15)
=100-90 = 10 °/•
Weight of sulphur=(10/100)×3
=3/10 = 0.3 kg =300 g
Weight of nitre=(75/100)×3
=225/100 = 2.25 kg =2250 g
