# 2.A mixture of paint is prepared by mixing 1 part of red pigments with 8 parts of base. In the following table, find the parts of base that need to be added.

Answer :

Let the number to be filled in the blanks be a, b, c and d respectively.
Therefore, $$\frac{1}8=\frac{4}a$$

$$\Rightarrow a=32$$

$$\frac{1}8=\frac{7}b$$

$$\Rightarrow b=56$$

$$\frac{1}8=\frac{12}c$$

$$\Rightarrow c=96$$

$$\frac{1}8=\frac{20}d$$

$$\Rightarrow d=160$$

Hence, we have the required value of bases as:
