A) 55
B) 60
C) 62.5
D) 64
Correct Answer: B
Solution :
In the original mixture, water\[=60\,\,cc\] Glycerine\[=180\,\,cc\] Let \[x\,\,cc\] of water be mixed. \[\therefore \] \[\frac{60+x}{180}=\frac{2}{3}\] \[\Rightarrow \] \[180+3x=360\] \[\Rightarrow \] \[3x=360-180=180\] \[\therefore \] \[x=\frac{180}{3}=60\,\,cc\]You need to login to perform this action.
