Answer 2

Let the length of the new parts be y, 2y and 6y, respectively.

y+2y+6y=450

9y=450

y= 450/9

y=50cm

2y=100cm

6y=300cm

The difference between the lengths of the longest part and the shortest part=6y-y= 5y=250 cm

So, the difference between the lengths of the longest part and the shortest part is 250 cm

Therefore, None of the above is the correct answer.

Hope it helps you.
