Answer 2

Heya !!!




Length of pole = 90 m



Ratio of the part of pole which is to be paint with different colour = 5:6:7




Let X be common multiply to this ratio becomes 5X , 6X , 7X


★ Length of part which is to be paint with white color = 5X



★ Length of part which is to be paint with black color = 6X


★ Length of part which is to be paint with blue colour = 7X





Therefore,



Sum of each part = Length of pole




5X + 6X + 7X = 90





18X = 90



X = 90/18


X = 5 m





Length of white part of the pole = 5X = 5 × 5 = 25 m
