Detailed Solution

We have to find the value of x when it is given that the median of the data is 63.
29,   32,   48,   50,   x,   x + 2,    72,    78,   84,   95
Median of the given N samples is obtained by arranging them in ascending order.
There are 10 samples in the given data set, therefore N=10
As N is even,
median= N 2 th sample+ N 2 +1 th sample 2  
Substitute the value of median in the expression and solve for x
Question Image Hence the value of x is 62.
Therefore the answer is option (2).
