Question

if 8 meters cloth cost 250rs, find the cost of 5.8 meters of the same cloth​

Answer 1

$\sf \bigstar \underline \purple{Given:-}$

→ Cost of 8 meters cloth = 250Rs

$\sf \bigstar \underline \red{To \: Find:-}$

→ Cost of 5.8 meters cloth

$\sf \bigstar \underline \orange{Solution:-}$

→ Cost of 8 meters cloth = 250Rs

∴ Cost of 1 meter cloth = 250/8

= 31.25 Rs

→ So, Cost of 5.8 meters cloth = 5.8 × cost of 1 meter ( 5.8 × 31.25 )

= 181.25 Rs

Hence, the Cost of 5.8 meters cloth is ↷

$\boxed{ \red{181.25 \: Rs}}$

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
