The number of scarfs of length half metre that can be made from y metres of cloth is :
(a) 2y
(b) y/2
(c) y + 2
(d) y + 1/2

Solution:

Given, the length of the cloth is y metres.

We have to find the number of scarfs of length half meter that can be made from the cloth.

Length of one scarf = 1/2 m

Number of scarfs = length of cloth/length of scarf

= y/(1/2)

= 2y

Therefore, the number of scarfs is 2y.

✦ Try This: The number of scarfs of length 1/5 m that can be made from y metres of cloth is

Given, the length of the cloth is y metres.

We have to find the number of scarfs of length 1/5 meter that can be made from the cloth.

Length of one scarf = 1/5 m

Number of scarfs = length of cloth/length of scarf

= y/(1/5)

= 5y

Therefore, the number of scarfs is 5y.
