If a set consists of all positive digits less than or equal to 3 and of the squares of those digits, what is the mode of the set?
Choices:
A) 1  B) 2  C) 3  D) 4  E) 9
let set X= {1, 1.5, 2, 2.5, 3}   Set in question consists of even the squares of the digits contained in set X.   Hence required set = { 1, 1, 1.5, 2, 2.25, 2.5, 3, 4, 6.25, 9}   Mode of set= 1   1NSWER:1
