B Correct answer
Explanation

The ascending order of given numbers is  $ \displaystyle  \frac{1}{9} $,$ \displaystyle  \frac{5}{9} $,$ \displaystyle  \frac{11}{9} $


Here denominator is equal, so greater the numerator greater will be the value.

 $ \displaystyle \therefore  $ Required difference 
$ \displaystyle  \frac{11}{9} $-$ \displaystyle  \frac{1}{9} $=$ \displaystyle  \frac{10}{9} $

B Correct answer
Explanation

$x$ can have any values between $3$ and $4$ so it can be rational or irrational. 
option $c$=$0.9$  and options $A$ and $D$ are outside the given range.
Hence, correct answer is option $B=\sqrt11=3.3$.

The number of whole numbers between the smallest whole number and the greatest 2-digit number is:

  1. $101$
  2. $100$
  3. $99$
  4. $98$

D Correct answer
Explanation

The smallest whole number is $0$ and the two-digit greatest whole number is $99$.

So the numbers between $0$ and $99$ are $1,2,....,98$ i.e. there are $98$ whole numbers between $0$ and $99$.
