Question

If the median of x,2×4×is 12.Then find the mean of the data​

Answer 1

Answer:

14

Step-by-step explanation:

x, 2x, 4x

no. of terms(n) = 3, which is an odd no.

Therefore, median = {(n+1)/2}th term = {(3+1)/2}th term = (4/2)th term = 2nd term = 2x

But median = 12

i.e. 2x = 12

x = 6

Therefore, the data is

x,2x,4x = 6, 2×6, 4×6 =6,12,24

Mean= sum of terms/ no. of terms = (6+12+24)/3 = 42/3 = 14

I hope it helped you!! Thanks!!
