उत्तर

Let the parts of red pigment required to mix with 1800 mL of base be x.

The given information, in the form of a table, is as follows:

Parts of red pigment 1 x
Parts of base (in mL) 75 1800

The parts of red pigment and the parts of the base are in direct proportion.

Therefore, we obtain

`1/75 = x/1800`

=> x = `(1 xx 1800)/75`

=> x = 24

Thus, 24 parts of red pigments should be mixed with 1800 mL of base.
