Their median or average is 3.14.

X/7+x/5+x/3=3×3.14

=9.42

7x+5x/35+x/3=9.42

12x/35+x/3=9.42

36x+35x/105=9.42

71x/105=9.42

X=9.42×105/71

X=13.93

To get the medium we always arrange numbers in ascending and descending order.

We then take the middle number.

In this question the numbers have been placed in ascending order.

We can rewrite :

x/7 , x/5 , x / 3

The median is the middle term.

The middle term is x/5

from the question :

the median = 3.14

Now :

x/5 = 3.14

x = 3.14 × 5 = 15.7

= 15.7
