Question

2ft3 of clay was mixed into 7ft3 of soil containing 55% clay. What is the clay content of the mixture?

Answer 1

Given:

2 ft³ of clay was mixed into 7 ft³ of soil containing 55% clay.

To find:

Clay content of the mixture.

Solution:

We have,

55% of soil is clay. So,

Clay in soil= 55% of soil

`\text{Clay in soil}=(55)/(100)* 7`

`\text{Clay in soil}=(385)/(100)`

`\text{Clay in soil}=3.85`

2 ft³ of clay was mixed into the soil. So, the total clay content of the mixture is

`2+3.85=5.85\text{ ft}^3`

Therefore, the clay continent in the mixture is 5.85 ft³.
