A) 7.5
B) 5.5
C) 10
D) 16
E) None of these
Correct Answer: E
Solution :
P : Q 3x 4x Now, \[3x\times \frac{120}{100}+2:4x\times 3+2\] \[=\left( \frac{18x}{5}+2 \right):(12x+2)\] \[=(3.6x+2):(12x+12)\] According to the question \[\frac{3.6x+2}{12x+2}=\frac{3}{7}\] \[\Rightarrow \]\[25.2x+14=36x+6=36x+6\] \[\Rightarrow \]\[10.8x=8\] \[\Rightarrow \]\[x=\frac{8}{10.8}=\frac{80}{108}=\frac{20}{27}\] \[\therefore \]\[Q=4x=\frac{80}{27}\]You need to login to perform this action.
