Solution
The correct option is
C
(
−
10
,
∞
)
The given inequality is,
1
x
+
10
>
10
We know that
1
>
0
Thus, numerator is greater than 1. For LHS to be positive, denominator must be greater than zero.
∴
x
+
10
>
0
∴
x
>
−
10
Thus, Interval of the solution is,
(
−
10
,
∞
)
Thus, Answer is option (C)
