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

$\text{Clay in soil}=\dfrac{55}{100}\times 7$

$\text{Clay in soil}=\dfrac{385}{100}$

$\text{Clay in soil}=3.85$

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.
