Step-by-step explanation:
According to the given problem,
Quantity of nitrate = 75%
Quantity of Sulphur = 10 %
Quantity of Charcoal = ( 100 - 75 - 10 ) %
= 100 - 85
= 15 %
Amount of Charcoal = 15 % of 8kg of gun powder
= 15% × 8 kg
= ( 15 /100 ) × 8 kg
= ( 120 / 100 ) kg
= 1.2 kg
Therefore,
Amount of Charcoal in 8kg gun powder = 1.2 kg
I hope this helps you.
