Solution

The correct option is A 45
$Let the unknown number be x . 10 more tha twice a number can be represented as 10 + 2 x .$

$According to the question, 10 + 2 x = 100$

$By subtracting 10 on both the sides of the equation, we get, \Rightarrow 10 + 2 x - 10 = 100 - 10 \Rightarrow 2 x = 90 By dividing 2 on both the sides, we get, \frac{2 x}{2} = \frac{90}{2} \Rightarrow x = 45$
