A) \[\frac{1}{7}\]
B) \[\frac{2}{7}\]
C) \[\frac{5}{7}\]
D) \[\frac{2}{5}\]
Correct Answer: B
Solution :
Let the fraction be x. According to the question, \[\frac{x}{3}-x\times \frac{3}{5}=\frac{32}{75}\] \[\Rightarrow \] \[\frac{5x}{3}-\frac{3x}{5}=\frac{32}{75}\] \[\Rightarrow \] \[\frac{25x-9x}{15}=\frac{32}{75}\Rightarrow \frac{16x}{15}=\frac{32}{75}\] \[\therefore \] \[x=\frac{32}{75}\times \frac{15}{16}=\frac{2}{5}\] Correct answers\[=\frac{2}{5}\times \frac{3}{5}=\frac{6}{25}\]You need to login to perform this action.
