Answer 1

Answer:

The cost of 30 pencils is ₹ 45

Step-by-step explanation:

Given information,

The cost of 12 pencil is ₹ 18

We have to find out the cost of 12 pencils.

As,

The cost of 12 pencils = ₹ 18

The cost of one pencil = $\frac{the \: cost \: of \: 5 \: pencile}{5}$

The cost of 1 pencil = $\frac{18}{12}$

The cost of 1 pencil = 1.5

The cost of 30 pencils= The cost of 1 pencil × 30

The cost of 30 pencils = 1.5 × 30

The value of 30 pencils = 45.0
