Question

Cost of 5/3 meters of cloth is rs 20, what is the cost of 1 2/5 meters of cloth?

Answer 1

The cost of 5 / 3 meters of cloth is given to be Rs. 20

We will first find the cost of 1 meter cloth

5 / 3 meter = Rs. 20

1 meter = 20 × 3/5

           = Rs. 12

Now, we have to find the cost of $1\frac{2}{5}$ meter cloth

We will first convert the mixed fraction into an improper fraction

$1\frac{2}{5}= \frac{7}{5}$

So, 1 meter = Rs. 12

     7 / 5 meter = 12 × 7/5

                       = Rs. 16.8

Hence, the cost of $1\frac{2}{5}$  meter cloth will be Rs.16.8

Answer 2

As per the data given in the question, we have to determine the cost of $1\frac{2}{5}.$meters.

The cost of $5 / 3$ meters of cloth is given to be $Rs. 20$

We will first find the cost of 1 -meter cloth

$5 / 3 meter = Rs. 20$

So, $1 meter =20 \times 3 / 5 = Rs. 12$

Now, we have to find the cost of $1 \frac{2}{5}$meter cloth

We will first convert the mixed fraction into an improper fraction

$=1 \frac{2}{5}=\frac{7}{5}$

so, $1$ meter=$Rs.12.$

then, 7 / 5 meter clothes cost will be

$=12\times\frac{7}{5}\\=16.8rs.$
