Question 307355
let the data values to be added be a, b & c.

for mean to be 92 

(70+100+a+b+c)/5=92

for mode to be 91 among the five values the maximum occurring value should be 91

so there should be either three or atleast two 91's among the five

if all a,b, and c are = 91 then their mean will not be = 92

so two are = 91

let a= 91 and b=91 

now (70+91+91+100+c)/5=92

=>  352+c=460

so c=108

now we will get that the values will be [ 70 91 91 100 108 ] Ans

also the median the center one when arranged in asc or dec order is 91 as required.
