A) Rs. 200
B) Rs. 300
C) Rs. 400
D) Rs. 450
Correct Answer: C
Solution :
(c) Let the first prize be x. \[\therefore \] Second prize \[=\text{ }\frac{1}{2}x\text{ }.\]Third prize \[=\text{ }\frac{3}{4}x\] \[\therefore \,\,\left( x+\frac{x}{2}+\frac{3x}{4} \right)=900\] \[\Rightarrow \,\,\frac{8x+4x+6x}{8}=900\Rightarrow 900\Rightarrow \frac{18x}{8}=900\] \[\Rightarrow \,x=\frac{900\times 8}{18}=400\]You need to login to perform this action.
