Choose the correct answer.
If |x - 1| > 5, then:
If |x - 1| > 5, then:
- A$\text{x}\in(-4, 6)$
- B$\text{x}\in[-4,6]$
- C$\text{x}\in[-\infty,-4)\cup(6,\infty) $
- D$\text{x}\in[-\infty,-4)\cup[6,\infty) $
Solution:
Given that |x - 1| > 5
⇒ (x - 1) < -5 or (x - 1) > 5
⇒ x < -5 + 1 or x > 5 + 1
⇒ x < -4 or x > 6
$\Rightarrow\text{x}\in[-\infty,-4)\cup(6,\infty) $

Let R be set of points inside a rectangle of sides a and b (a, b > 1) with two sides along the positive direction of x-axis and y-axis. Then
If A and B are coefficient of xn in the expansions of (1 + x)2n and (1 + x)2n – 1 respectively, then $\frac{\text{A}}{\text{B}}$ equals:
