Practicing Success
The marks of Eleven students in ascending order for a test are given below with Median as 36, the value of k is: 10, 12, 16, 25, 28, k + 3, k + 5, 43, 45, 47, 53. |
36 37 35 33 |
33 |
10, 12, 16, 25, 28, k + 3, k + 5, 43, 45, 47, 53. n = 11 (odd number) Median = \(\frac{(N + 1)}{2}\)th term ⇒ 36 = \(\frac{(11 + 1)}{2}\)th term ⇒ 36 = \(\frac{(12)}{2}\)th term ⇒ 36 = 6th term ⇒ 36 = k + 3 ⇒ k = 36 – 3 ∴ k = 33 |
