B) 31 : 151
C) 125 : 51
D) 121: 39
Correct Answer: D
Solution :
Total quantity of milk\[=2\times 0.9+5\times 0.8+9\times 0.7=12.1\,\,L\] Milk concentration in the resultant mixture \[=\frac{12.1}{2+5+6}\times 100=75.625%\] Water concentration in the resultant mixture \[=100-75.625%=24.735%\] Milk : Water \[=\frac{75625}{24735}=121:39\]You need to login to perform this action.
