A) 2.3 m
B) 2.5 m
C) 2 m
D) 3.2 m
Correct Answer: A
Solution :
The red part is \[1\frac{2}{5}\] times the blue part \[=\frac{7}{5}\] (Blue part) Total length of the pole = Blue part + Red part = Blue part + \[\frac{7}{5}\] (Blue part) \[=\left( 1+\frac{7}{5} \right)\] (Blue part) = 5.52m \[\therefore \] Blue part \[\text{= 5}\text{.52 m }\!\!\times\!\!\text{ }\frac{\text{5}}{\text{12}}\text{= 2}\text{.3 m}\]
