A) \[(-\infty ,3)\]
B) \[(1,3)\]
C) \[(4,\infty )\]
D) \[(-\infty ,-1)\]
Correct Answer: C
Solution :
[c] \[x+7<2x+3\] \[2x+4<5x+3\] \[\left. \Rightarrow 4<x\,\,\,\,\,\,\,\,\, \right|\,\,\,\,\,\,\,\,\,\,1<3x\Rightarrow x>\frac{1}{3}\] so, \[x>\frac{1}{3}\,\,and\,\,x>4\,\,\,\,\therefore \] x lies in \[(4,\infty )\].You need to login to perform this action.
