Question

A piece of string is 40cm long. It is cut into three pieces. The longest piece is 3 times as long as the middle-sized piece and the shortest piece is 23 cm shorter than the longest piece. Find the length of the shortest piece in cm.

Answer 1

Answer:

Its 4 cm.

Step-by-step explanation:

Suppose, the middle-sized string has the length=x

So, the length of the longest piece of string=3x and  

The length of the shortest piece of string=3x-23

Now, adding all the pieces of string, we get:

x+3x+3x-23=40

7x=40+23

7x=63

x=9

Hence, the length of the shortest piece=3x-23=4 cm

Therefore,  4 is correct.
