    The three sides of a triangle are 10, 100 and x. Which one of the following is correct?

    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. \[\therefore \]      \[90<x<110\]
