Among 10.,15,20,25,15,x
15 is reapeated twice .So we can say that 15 will be the mode.The value of x will be equal to 15.
In the same way arranging the numbers in ascending order 10,15,15,15,20,25 we get 15 as the median .
Mode and median are same.Thus we can confirm x as 15
Mean of ungrouped data is sum of observation divided by number of observation.
in this case it is
=10+15+15+15+20+25/6
=100÷6
=16.6(or)50/3
