Question 615725
let the three values to be added be a,b & c 

now given mean is 96

 so, (70+a+b+c+100)/5 = 96 ----- eq.1

also given the median is 97, so if all the five numbers are ordered in either ascending order or descending order, the 3rd(median) value will be 97.

also given the mode is 97, so the value that is repeating or occurring the maximum no. of times is 97.

so, here out of the three values a,b,and c at least two should be 97.


from eq.1 70+a+97+97+100= 96*5

        =>364+a = 480
  
        => a = 116
   
so the data values are 70,97,97,100,116
