Question

One third of the pole is painted red,one fifth is painted blue and the rest is painted white. If the portion which is painted white is 210cm long, what is the length of the pole?

Answer 1

Answer:

Hence, The length of the pole is 450c.m.

Step-by-step explanation:

Let's consider the total length of the pole be 1.

Given,

Part of pole painted in red= 1/3

Part of pole painted in blue= 1/5

hence, the remaining part of the pole

= 1-(1/3+1/5)

=1 - 8/15

=7/15

Acc. to the problem,

• 7/15 part of the pole is equal to 210c.m.

then, 1 part of the pole is equal to (210×15/7)c.m

• i.e. 450 c.m.

Hence, The length of the pole is 450c.m.
