Question

A piece of cloth is 5 metre long. after washing, it shrinks by 1 /2 of its total length. what is the length of the cloth after washing?

a.3315 m

b.44 /5 m

d.7 m

Answer 1

i think question not right .it may be 1/25 in place of 1/2 Origional length of cloth =5 m 
Length reduction after washing = 1/25 of the origional length 
Reduction in length after washing = 
1/25 x 5 m 
=1/5 = 0.2 m 
Length of cloth after washing 
= 5 m - 0.2 m 
= 4.8 m (ans)

Answer 2

given it shrinks half i.e
$\frac{5}{2} = 2.5$
it shrinks 2.5 m
so length after washing should be 5-2.5=2.5
2.5 is the answer
