Do as directed:

If 8 pens rupees 240, Find the cost of 12 pens​

Answer 1

Answer:

360 rupees.

Step-by-step explanation:

cost of 8 pens = 240/-

cost of 1 pen = 240/8 = 30/-

∴ cost of 12 pens = 30 × 12

                             = 360/-

Answer 2

• As per the data given in the question, we have to find the cost price of $12$ pens.

       Given data:- $Cost\ price\ of\ 8\ pens\ are\ 240.$

       To find:- the cost price of $12\ pens.$

       Solution:-

• Firstly, we have to find the cost price of a single pen then we will calculate the cost price of $12$ pens.

       The cost price of a single pen is

       $=\frac{240}{8}\\= 30.$

    So, the cost price of $12$ pen is

      $=12\times30\\=360.$

  Hence, the cost price of $12$ pens will be $360.$
