Question

3. The cost of 17 metres of cloth is Rs 2303.50, What length of this cloth can be purchased for Rs 8401?

Answer 1

Answer:

Correct option is

A

121 metre

Let x meter be the length of the cloth that can be purchased for Rs.302.50.

Length ( in m ) 97 x

Cost ( in Rs ) 242.50 302.50

Since, the length of the cloth and its cost are in direct variation, we have :

⇒

x

97

=

302.50

242.50

⇒ 97×302.50=x×242.50

⇒ x=

242.50

97×302.50

⇒ x=

242.50

29342.50

⇒ x=121

∴ The required length will be 121 meter.
