Answer 2

The cost of 140 m of wire is Rs 190.4

280 meter of wire will cost Rs 380

Solution:

Given that,

Cost of 154 m of wire is Rs 209

Then,

$\text{Cost of 1 meter } = \frac{209}{154 } \\\\\text{Cost of 1 meter } = 1.36$

Find the cost of 140 m of wire

$\text{Cost of 140 meter } = 1.36 \times 140 \\\\\text{Cost of 140 meter } = 190.4$

Find Rs.380 will be cost of how long wire

$380 = x \times 1.36\\\\x = \frac{380}{1.36} \\\\x = 279.411 \approx 280$

Thus 280 meter of wire will cost Rs 380
