Answer 1

Answer:

900 gram sulphur was in 9 kg gunpowder

Answer 2

Answer:Amount of nitrate in gunpowder = 75%

Amount of sulphur in gunpowder = 10%

Remaining is Charcoal , So percentage of Charcoal = 100-(75+10) =(100-85) = 15%

We have to find Amount of Charcoal in 8kg of gunpowder , gunpowder has 15% Charcoal. So amount of Charcoal in 8kg gunpowder =

15% of 8

or, 15/100 × 8

or, 3/20 × 8

or, 3/5 × 2

or, 6/5

or , 1.2kg

Answer→ 8kg of gunpowder had 1.2 kg of Charcoal.
