Question
Find the median of the following observations: 42, 38,
45, 50, 48, 52, 47, 46, 44Solution
Ascending order of observations: 38, 42, 44, 45, 46, 47, 48, 50, 52
Number of observations = 9 (odd number).
Median formula for odd observations:
Median = [(n + 1) ÷ 2]th term
For n = 9, the 5th term is 46.

(1/5)(40% of 800 – 120) = ? × 5
Determine the value of 'p' in following expression:
720 ÷ 9 + 640 ÷ 16 - p = √121 X 5 + 6²- 7(23 × 8) – (13 × 5) + 67 =? x 6         Â
Evaluate
64 ÷ 4 of 5 of [10 ÷ 5 of (9 ÷ 3 + 2)] + (9 ÷ 3 + 1)
?2 = (1035 ÷ 23) × (1080 ÷ 24)Â
- Evaluate: 156 ÷ 12 × 4 + 180 – 40% of 350
520% of 360 – 12% of 400 = ? x 4
- What will come in place of (?) in the given expression.
(⅗ of 450) – (⅖ of 300) = ? 45% of 1020 + ?% of 960 = 747
345 × 20 ÷ 4 + 28 + 60 = ?Â
