A) 4 : 15
B) 3: 7
C) 6: 7
D) None of these
Correct Answer: D
Solution :
By law of mixture, \[\therefore \] \[\frac{\frac{3}{8}-x}{x-\frac{1}{4}}=\frac{3}{2}\] \[\Rightarrow \] \[\frac{3}{4}-2x=3x-\frac{3}{4}\] \[\Rightarrow \] \[5x=\frac{6}{4}=\frac{3}{2}\] \[\Rightarrow \] \[x=\frac{3}{10}\]You need to login to perform this action.
