3 /5

part of a pole is painted blue,

3/ 10

part is painted green and the remaining 105 m is painted red, then find the total length of the pole

Solution:

Let the total length of the pole be x m
The part painted blue

= {3x}/5

The part painted green

={3x}/10

∴x={3x}/5+{3x}/10+105

10x = 6x + 3x + 1,050

10x = 9x + 1,050x = 1,050
