Question

if the cost of 80m cloth is 300 rs then what will be the cost of 5.12cm ?

Answer 1

Answer:0.255 RS

Step-by-step explanation:

Cost of 80m cloth=400 RS.

Cost of 1m cloth= 400/80 RS

Thus, cost of 1m cloth= 5 RS

As 1cm=1/100 m

Hence,5.12 cm=5.12/100 m

Thus cost of cloth,

=0.051*5

=0.255 RS

Answer 2

Answer:

Rs. 0.192

Step-by-step explanation:

Cost of 80m cloth = Rs. 300

∴ cost of 1m cloth = Rs. (300/80)

                             = Rs. 3.75

Now, 1m =100cm

∴ 5.12cm = (5.12/100)m

               = 0.0512 m

So, 0.0512×3.75

    = 0.192

∴ the cost of 5.12cm cloth is Rs. 0.192
