Question

A mixture of sugar and salt contains 30% sugar. Find the weight of salt in 20 kilograms of the mixture.

• A. $\text{16 kg}$
• B. $\text{12 kg}$
• C. $\text{6 kg}$
• D. $\text{14 kg}$

Answer 1

The correct option is D $\text{14 kg}$

Percentage of sugar in the mixture $=30\%$
Therefore, percentage of salt in the mixture $=100-30=70\%$
Weight of salt in 20 kg of the mixture $=\frac{70}{100}\times 20=14kg$
