A) \[x=\frac{2}{5},\]\[y=\frac{3}{5}\]
B) \[x=\frac{2}{3},\]\[y=5\]
C) \[x=\frac{2}{5},\]\[y=\frac{5}{3}\]
D) \[x=\frac{3}{5},\]\[y=\frac{2}{5}\]
Correct Answer: A
Solution :
Here, \[x+2y=1.6\]and \[x+\frac{y}{2}=\frac{z}{10}\] (Given) \[\Rightarrow \] \[10x+20y=16\] and \[10x+5y=7\] On subtracting, we get \[\Rightarrow \]\[y=\frac{3}{5}\] From Eq. (i) \[x+2y=\frac{8}{5}\] Put \[y=\frac{3}{5},\]\[x+\frac{6}{5}=\frac{8}{5}\] \[\Rightarrow \] \[x=\frac{2}{5}\]You need to login to perform this action.
