Question

12. 20% of length of a flagpole is painted green, 45% is painted yellow and the
remaining red. If the length of the pole is 18 m, what length of it is painted red?
​

Answer 1

Answer:

Step-by-step explanation:

Total length of a pole= 18 cm ( No matter if it is in metre answer will be same)

% of pole painted in green = 20%

% of pole painted in yellow =45 %

% of pole painted red = 20% + 45% - 100 % ( 100 will be there because percentage is over all in 100 or % )

Continuation : 20% + 45% - 100%

                      = 65% - 100%

                      = 35 %

Length of pole painted red = 35 / 100 x 18

                                             = 63 /10

                                             =6.3cm

So, the length of a pole painted in red will be 6.3 cm
