A) \[10<x<100\]
B) \[90<x<110\]
C) \[90\le x\le 100\]
D) \[90\le x<110\]
Correct Answer: B
Solution :
We know, the sum of two sides is always greater than third sides. \[\therefore \] \[10+100>x,\]\[10+x>100\] and \[100+x>10\] \[\Rightarrow \] \[110>x,\]\[x>90\] and \[x>-110,\] but x cannot be negative. \[\therefore \] \[90<x<110\]You need to login to perform this action.
