The cost of 97 metre of cloth is Rs 242.50. What length of this can be purchased for Rs 302.50?

Answer»

Let the length of the cloth be x meter

Cost(Rs)242.50302.50
Length of cloth(m)97x

\(\frac{242.50}{97}\) = \(\frac{302.50}{x}\)

On cross multiplication, we get

242.50x = 97 x 302.50

x = \(\frac{97\times 302.50}{242.50}\)= 121

Therefore length of the cloth is 121 M
