Question

cost of 19/16 meters of wire is 171/2. find the cost of 5 meters of wire.

Answer 1

cost of 19/16 meter wire is 171/2

cost of 1 meter wire will be

= (171/2) × (16/19)

= 2736/38

= 72

so

cost of 5 meter wire will be

72×5 = 360

Answer 2

SOLUTION :

According to question,

Cost of 19/16 m of wire = 171/2

TO FIND :

Cost of 5 metres of wire.

Let us solve this problem by unitary method.

Cost of 1 metre wire will be =

$\frac{171}{2} \div \frac{19}{16}$

$\frac{171}{2} \times \frac{16}{19}$

$9 \times 8$

$72$

We have found that,

1 metre of wire costs = Rs 72

So,5 metres of wire will costs = Rs 72 x 5

• = Rs 360

Hence,

The costs of 5 m wire is Rs. 360
