Question

if 10,13,15,18,X+1,X+3,30,32,35,41 are ten observations in an ascending order with median 24 find the value of X.

Answer 1

Hello Friend !!!

If the median of even number of observations ( 10 observations ) = 24
⇒ ( x + 1 + x + 3 ) / 2 = 24
  ⇒ ( 2x + 4 ) / 2 = 24
⇒ 2x + 4 = 48
⇒ 2x = 44
⇒ x = 22 ( Ans )


Plz mark me as BRAINLIEST if u find it helpful !!!

Answer 2

x + 1 + x + 3 = 24
⇒ 2x + 4 = 24 
⇒ x = 10 ( Ans )
