A) 28
B) 29
C) 31
D) 35
Correct Answer: A
Solution :
Clearly, we have \[A=B-3\] ? (i) \[D+5=E\] ? (ii) \[A+C=2E\] ? (iii) \[B+D=A+C=2E\] ? (iv) \[A+B+C+D+E=150~\] ? (v) From Eqs. (iii), (iv) and (v), we get \[5E=150\] or \[E=30\] Putting \[E=30\] in Eq. (ii), we get \[D=25\] Putting \[E=30\] and \[D=25\] in Eq. (iv), we get \[B=35.\] Putting \[B=35\] in Eq. (i), we get \[A=32.\] Putting \[A=32\] and \[E=30\] in Eq. (iii), we get \[C=28.\]You need to login to perform this action.
