Question

• A. 20
• B. 19
• C. 21
• D. 22

Answer 1

Answer: (C)

21

Answer 2

First we write all the observation as 10, 18, 21, 35, 42. Since, number of observation = 5 (odd) $\therefore$ Median = $\left( \frac{n + 1}{2} \right)^{th}$ observation = $\left( \frac{6}{2} \right)$ =3rd observation = 21
