Question

A particular shade of paint is made by mixing 5 parts red paint and 7 parts blue paint. To make this shade, Shannon mixed 12 quarts of blue paint with 8 quarts of red paint. Did Shannon mix the correct shade?

Answer 1

Answer:

No, Shannon  didn’t mix the correct shade

Explanation:

Ratio required for the shade Red : Blue = 5 : 7

The ratio formed of Shannon must be equal to the above standard ratio

But Shannon’s ratio which was mixed for red and blue is

= Red : Blue  

= 8 : 12

= 2 : 3, which is not equal to 5 : 7.

Therefore it is proved that Shannon mixing does not matches with the required mixing ratio which is 5:7.
