A) 6 L
B) 6.5 L
C) 5.5 L
D) 5 L
Correct Answer: D
Solution :
Water content in 40 L of mixture \[=40\times \frac{10}{100}=4\,L\] \[\therefore \] Milk content \[=40-4=36\,L\] Let x L of water is mixed. \[\therefore \] \[\frac{4+x}{40+x}=\frac{20}{100}\] \[\Rightarrow \] \[\frac{4+x}{40+x}=\frac{1}{5}\] \[\Rightarrow \] \[20+5x=40+x\] \[\Rightarrow \] \[4x=20\] \[\Rightarrow \] \[x=5\,L\]You need to login to perform this action.
