A) 34
B) \[56\frac{2}{3}\]
C) 85
D) 51
Correct Answer: D
Solution :
Let the length of first part = x m \[\therefore \] The length of another part \[=(85-x)m\] According to question, \[x=\frac{2}{3}(85-x)\] \[\Rightarrow \] \[3x=170-2x\] \[\Rightarrow \] \[x=\frac{170}{5}=34\] \[\therefore \] The length of first part = 34 m and the length of second part \[=85-34\] \[=51\,m\]You need to login to perform this action.
