Question

if 30% of a length of fabric costs ₹126, the total length of the fabric is?

Answer 1

420 rupees just multiply 126 with 100/30

Answer 2

Answer:

420 rupees.

Step-by-step explanation:

Let x be the cost of full length of the fabric,

Since, the cost of 30% of the length of the fabric

$=\frac{30\times x}{100}$

$=\frac{3x}{10}$

According to the question,

$\frac{3x}{10}=126$

$\implies x = \frac{1260}{3}=420$

Hence, the total length of the fabric is of ₹420.
