Answer 2

Given,

The cost of 19/4 metres of wire = Rs. 171/2

To find,

The cost of 1 metre of the wire.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following:

The cost of 19/4 metres of wire = Rs. 171/2

So, to find the cost of 1 metre of the wire we will divide the total cost by the given length of the wire.

19/4 metres = Rs. 171/2

1 metre = Rs. $\frac{171}{2} \div \frac{19}{4}$

1 metre = Rs. $\frac{171}{2} \times \frac{4}{19}$

1 metre = Rs. 18

Hence, the cost of 1 metre of the wire is Rs. 18.
