A) 4 L
B) 8 L
C) 16 L
D) 40 L
Correct Answer: D
Solution :
Let the initial quantity of liquids A and B in the jar be 4x and x L respectively. After taking out 10 L of the mixture, Liquid \[A=4x-\frac{4}{5}\times 10=(4x-8)L\] Liquid \[B=4x\times \frac{1}{5}\times 10=(4x-2)L\] After pouring 10 L of Liquid B, \[\frac{4x-8}{4x-2+10}=\frac{2}{3}\] \[\Rightarrow \] \[12x-24=8x+16\] \[\Rightarrow \] \[4x=40\] \[\Rightarrow \] \[x=\frac{40}{4}=10\] \[\therefore \] Quantity of Liquid \[A=4x=4\times 10=40L\]You need to login to perform this action.
