If the median of data (arranged in ascending order) 31, 33, 35, x, x+10, 48, 48, 50 is 40, then find value of x. -Maths 9th

1 Answer

Answer :

Given data is 31, 33, 35, x, x+10, 48, 48, 50  Number of observation = 8 (even) Median = Value of (8/2)th  observation + Value of (8/2+1)th observation / 2 Value of 4th  observation + Value of 5th  observation / 2 = x + x + 10 / 2 = x + 5 ∴  x + 5 = 40 ⇒ x = 35
