Question

if 40 metres of cloth cost rupees 1940 how many metres can be bought for rupees 727.50​

Answer 1

Let the length of cloth can be bought for 727.50 be X.

40: 1940 :: X : 727.50

40 * 727.50 = 1940 * X

$x = \frac{40 \times 1940}{727.50} \\ x = \frac{77600 \times 100}{72750} \\ x = \frac{776000}{7275} \\ x = 106 \frac{4850}{7275} \\ x = 106 \frac{194}{291}$
