Given :

To prepare gunpowder 65% nitre, 20% charcoal and 15% sulphar are needed.

To Find :

Quantity of ingredients present in 50 kg of gunpowder.

Solution :

In 50 kg of gunpowder the quantity of nitre

= 65% of 50

= $\frac{65}{100}\times 50$

=  32.5 kg

In 50 kg of gunpowder, the quantity of charcoal

= 20% of 50

= $\frac{20}{100}\times 50$

= 10 kg.

In 50 kg of gunpowder, the quantity of sulphar

= 15% of 50

= $\frac{15}{100}\times 50$

= 7.5 kg

In 50 kg of gunpowder 32.5 kg of nitre, 10 kg of charcoal and 7.5 kg of sulphar.
