To solve this problem, let's assume the number as "x".
According to the given information, one-seventh of the number exceeds its eleventh part by 100. Mathematically, we can represent this as:
$\frac{x}{7} - \frac{x}{11} = 100$
To simplify the equation, we need to find a common denominator, which is 77:
$\frac{11x}{77} - \frac{7x}{77} = 100$
Now we can combine the two fractions:
$\frac{11x - 7x}{77} = 100$
Simplifying further:
$\frac{4x}{77} = 100$
To isolate x, we can cross multiply:
$4x = 7700$
Dividing both sides by 4:
$x = 1925$
Therefore, the correct answer is option B) 1925.
