A) \[-\frac{7}{2}\]
B) \[3\frac{1}{2}\]
C) \[\frac{7}{4}\]
D) \[-3\frac{1}{4}\]
Correct Answer: B
Solution :
\[1.32\,y+\,0.02y=1.19+y\] \[\Rightarrow \] \[1.34\,y=1.19+y\] \[\Rightarrow \] \[1.34-\,y=1.19+y\] \[\Rightarrow \] \[1.34-\,y=1.19\] \[\Rightarrow \] \[y=\frac{1.19}{0.34}=\frac{119}{34}=\frac{7}{2}\] \[\therefore \] \[y=3\frac{1}{2}\]You need to login to perform this action.
