A) 86
B) 68
C) 43
D) 34
Correct Answer: B
Solution :
Let \[\frac{2}{3}\] rd of number \[=x\] Since, both the fractions \[\frac{3}{17}\] and \[\frac{2}{3}\] are to be found out for the same number. \[\therefore \] \[\frac{\text{Fractional number}}{\text{Its related fraction}}=\frac{\text{Another fractional number}}{\text{Its related fraction}}\] = Original number (always) \[\Rightarrow \] \[\frac{18}{3/17}=\frac{x}{2/3}\] \[\therefore \] \[x=68\]. Hence, two-third of the number is 68.
