Question

gunpowder contains 75% nitre and 10% sulphur. Find the amount of gunpowder which carries 9kg nitre. What amount of gunpowder would contain 2.5 kg sulphur?​

Answer 1

Let the amount of gunpowder =x

x of 75% =9kg

x of 75/100 =9

3x/4= 9/1

3x =9×4

x= 36/3

x= 12 kg

And,

x of 10% = 2.5 kg

x of 10/100 = 2.5 kg

x/10 = 2.5

x= 2.5 × 10

x= 25 kg
