Question

if 8 meter cloth cost 250 find cost of 5.8 meter

Answer 1

cost of 8m cloth=250

by using unitary method,

cost of 1m cloth= 8/250

=31.25

therefore, cost of 5.8m cloth = 5.8*31.25

=181.25

Answer 2

Let the cost of 5.8 m cloth be ₹ x

So,

Length (in m) 8 5.8

Cost of cloth (in ₹) 250 x

We know that it is a direct variation.

So, 8: 250 = 5.8: x

8/250 = 5.8/x

x = (5.8 × 250)/8

= ₹181.25
