#21%#

Explanation:

Since "#%#" means out of a hundred , that means the given percentages, #37%#, #42%#, and the undecided percentage should add up to one hundred. If we subtract #37%# and #42%# from #100%#, we can find the undecided percentage.

Thus,

#100%-37%-42%#

#=63%-42%#

#=color(green)(|bar(ul(color(white)(a/a)21%color(white)(a/a)|)))#
