Step-by-step explanation:

To find : cost of 6 pens​ .

Given :  10 pens cost for 80 Rs.

Solution :

• As per given data we know that , cost of 10 pens is 80 Rs. We have to find cost of 6 pens​ .  
• We write as , cost of 10 pens = $80\ Rs$
• Firstly we find cost of $1$ pen by dividing  $80\ Rs$  by $10$ .
• Cost of $1$ pen $= \frac{80}{10}$  

                               $= 8\ Rs$

• As we know that  $1$ pen costs for $8\ Rs$ now we can find cost of $6$ pens​  by multiplying number of pens by cost of  $1$ pen

• Cost of $6$ pens​ = $6\times 8$

                                 $= 48\ Rs$

Answer 2

Answer:

Therefore the cost of 6 pens is Rs.48.​

Step-by-step explanation:

As per the data provided in the given question

The given data is as follows

The cost of 10 pens is Rs.80

We have to find the cost 6 pens.

At first, we will find the cost of 1 pen.

So we will divide 80 by 10 we get,

cost of 1 pen,

$=\frac{80}{10}$

We will cancel zero from the above equation

Further, we get

$=\frac{8}{1} \\= Rs.8$

Now we will find the value of 6 pens

We will multiply 8 into 6 we get

$=8\times6\\=Rs.48$

Therefore the cost of 6 pens is Rs.48.​
