Question

I bought 4 meters of cloth from a shop, but when I actually counted the cloth at home, it got less. Why ?​

Answer 1

Answer:

it is not possible..

maybe there is difference I the object the shopkeeper using and you use for measuring the cloth.. but it can also be done by washing the Cloths.

Answer 2

  Because, it does not have the chemical composition of cloth and the change is only the state, size, shape, color texture or the smell or all substances that undergo physical change

Given:

4 meters of cloth from a shop is brought at a price of 35 rupees

To Find:

Why it is reduced when the cloth is cut

Solution:

Imagine a piece of cloth costs Rs. 35

If the piece were 4 m longer and each meter costs Re. 1 less, the cost would remain unchanged

 Let the length of the piece be xm

⇒  Cost price of cloth =Rs.35

Cost price of 1m cloth = 35/x

According to the assumption,

(x+4)(35/x - 1) = 35

x 2 +4x−140=0

x2+14x−10x−140=0

 x(x+14)−10(x+14)=0

x=10

∴  The length of the piece is 10m.
