Solution

The correct option is B All of the above
the real number includes
(1) Whole numbers ( 0,1,2,3,4....etc)
(2) Rational numbers ( $\frac{3}{4}, 0.125, 0333 e t c$ )
(3) Irrational numbers ( $π, \sqrt{3}, 2 + \sqrt{3} e t c$ )
Then all the number given in question are Real numbers
Answer is (D) All of above are real numbers

Q. Find the median of the following numbers

11, 13, 8, 10, 15, 18, 12, 7, 9, 16

Verify the following :

(i) $\frac{3}{7} \times (\frac{5}{6} + \frac{12}{13}) = (\frac{3}{7} \times \frac{5}{6}) + (\frac{3}{7} \times \frac{12}{13})$
(ii) $\frac{- 15}{4} \times (\frac{3}{7} + \frac{- 12}{5}) = (\frac{- 15}{4} \times \frac{3}{7}) + (\frac{- 15}{4} \times \frac{- 12}{5})$
(iii) $(\frac{- 8}{3} + \frac{- 13}{12}) \times \frac{5}{6} = (\frac{- 8}{3} \times \frac{5}{6}) + (\frac{- 13}{12} \times \frac{5}{6})$
(iv) $\frac{- 16}{7} \times (\frac{- 8}{9} + \frac{- 7}{6}) = (\frac{- 16}{7} \times \frac{- 8}{9}) + (\frac{- 16}{7} \times \frac{- 7}{6})$
