A) 70 L
B) 80 L
C) 100 L
D) 140 L
Correct Answer: A
Solution :
Let in a mixture of 80L, Milk \[=3xL\] and water \[=xL\] By given condition, \[80=3x+x=4x\] \[\Rightarrow \] \[x=20\,L\] \[\therefore \] Water \[=20\,L\] and Milk \[=60\,L\] If x L of water is added, then ratio to milk and milk \[=2:3\] \[\therefore \] Water in new mixture \[=\text{(}20+x\text{) }L\] Now, \[\frac{60}{20+x}=\frac{2}{3}\] \[\Rightarrow \] \[180=40+2x\] \[\Rightarrow \] \[2x\text{ }=140\] \[\Rightarrow \] \[x=70\,L\]You need to login to perform this action.
