A) 16
B) 13
C) 14
D) 15
Correct Answer: B
Solution :
\[A+B+C+D=60\] \[A=\frac{B+C+D}{2}\] \[\Rightarrow \] \[3A=60\Rightarrow A=Rs.20\] \[B=\frac{A+C+D}{3}\] \[\Rightarrow \] \[4B=60\Rightarrow B=Rs.15\] \[C=\frac{A+B+D}{4}\] \[\Rightarrow \] \[5C=60\Rightarrow B=Rs.12\] \[D=60-(20+15+12)=Rs.\,13\]You need to login to perform this action.
