Answer:

Hence, there will be total of 8 blue pens in the box.

Step-by-step explanation:

In context to question asked,

We have to determine the number of blue balls.

As per question,

It is given that,

Box has 12 pens

As one - third of pens are red

So, total number of red ball pens will be $=\frac{1}{3}\times 12 = 4$

As the rest pens are of blue colour

So, total number of blue colour pens will be $=12-4 = 8\:Pens$
