Answer 1

The cost of pencils per score will be Rs. 50.

----------------------------------------------------------------------------------------

Let's understand a few concepts:

To solve the given problem we will take the help of the following conversion rates:

$\boxed{\bold{1 \:dozen = 12 }}$

$\boxed{\bold{1 \:score = 20}}$

----------------------------------------------------------------------------------------

Let's solve the given problem:

The cost of 1 dozen pencils = Rs. 30

We know,

1 dozen pencils = 12 pencils

So,

The cost of 12 pencils = Rs. 30

∴ The cost of 1 pencil = $\frac{30}{12} = \frac{5}{2} = Rs. \:2.5$

Also, we know that,

1 score pencils = 20 pencils

Now,

The cost of 20 pencils will be,

= $20 \times [Cost \:of \:1 \:pencil]$

= $20 \times Rs. \:2.5$

= $\bold{Rs. \:50}$

Thus, the cost of pencils per score​ will be Rs. 50.
