Question

On washing 40 m cloth it shrunk by 0.5% what is the new length of the cloth

Answer 1

1% = 4m

0.5 % = 2m

= 40 - 2

= 38

The answer is 38 m

Answer 2

The 40 m cloth shrunk by 0.5 percent.

Let the new length be 'p' meter.

40 m - (0.5/100) × 40 = p

40 m - 0.2 m = p.

39.8 m = p

The new length of the cloth is 39.8 m.
