The rod

The rod is painted in four colors. 55% of the bar is painted in blue or green, 0.2 of the rod, 1/8 is brown, and the remaining 45 cm of white. How long is the rod?

Correct answer:

x =  360 cm

Step-by-step explanation:


x-55/100x - 0.2 x - 1/8x = 45

x-55/100·x - 0.2·x - 1/8·x = 45

25x = 9000


x = 9000/25 = 360

x = 360
