Answer 2

Step-by-step explanation:

ANSWER

Let l be the length of the cloth and c be its cost.

Then, l∝c

∴l=kc   (where k is a constant of variation.)

Substituting l=24 and c=840

⇒24=k×840

⇒k=84024

⇒k=351

Now, taking c= Rs. 525 and k=351

⇒l=351×525

⇒l=15 m

Hence, the length of a cloth is 15 m.
