Question

If the median of x, 2x, 4x is 12, then find mean of the data
​

Answer 1

Answer:

Median = 2x, as it is middle term of the set

2x = 12

x = 6

So, x = 6

Let's substitute the value.

Mean = 6 + 12 + (4 × 6)/3

= 6 + 12 + 24/3 = 42/3

= 14

Thus, mean = 14

Answer 2

Step-by-step explanation:

mean = 2x it is middle term of set

2x = 12

therefore x = 6

let substitute the values

mean = 6+12+(4×6)÷3

= 6+14+24/3

= 42/3

= 14

therefore Mean =14
