Answer: 200cm long
Step-by-step explanation:
Let the length of the rod be x
red = 1/4 of the rod , which means 1/4 of x
orange = 2/5 of x
The remainder = x - (
+
)
= x - (
)
= 
yellow = 2/7 of the remainder , that is
yellow = 2/7 of 
yellow = 
and it was given that the yellow section was 20cm long , that is
