Question

if 1 meter cloth is rs 90 how much is 10 meter cloth?​

Answer 1

Answer:

let the length of cloth of 10meter be x

1 : 90 :: 10 : x

Product of extremes = Product of Means

1 × x = 90 × 10

1x = 900

x = 900

Answer 2

The cost of cloth is directly proportional to the number of metres bought.

So, if 5 metres cloth costs Rs48, then 1 metre cloth will cost Rs 48/5

And 23 metres will cost 23×Rs 48/5

=Rs220.8
