A) 250
B) 150
C) 200
D) 160
E) 180
Correct Answer: E
Solution :
\[\because \,\,x+2x+3x=600\times 3\] \[\Rightarrow \]\[6x=1800\] \[\therefore \]\[x=300\] \[\therefore \]\[A=300,\,\,B=600\] and\[C=900\] New total \[=(600\times 3)\times \frac{105}{100}=1890\] New quantity of\[A=300\times \frac{110}{100}=330\] New quantity of\[B=600\times \frac{80}{100}=480\] Now, new quantity of C \[=1890-(330+480)=1080\] \[\therefore \]Increase in the number \[=1080900\text{ }=\text{ }180\]You need to login to perform this action.
